The SG and ZG are not exactly the same though. Just from the pictures I can see that the bases are different. The SG has L-shaped legs and a bottom shelf while the ZG has square legs that are larger than the DLX legs but no bottom shelf. There were also different specs for many features. I took a picture of the ZG spec sheet at the store and compared it to the SG specs on the website and there are slight differences in capacities. For example ZG 3778 cubic inch - SG 4859, grilling area ZG 776- SG 811, hopper volume ZG 18 lbs - SG 22, ...

I've had my ys640 for almost a year now. I absolutely love it! I debated for a long time before my purchase. I'm an old school charcoal guy at heart. I used to have a gas grill and a coal pit. I got tired of replacing gas grills every few years and having two grills is cumbersome. I considered an egg but the pellet grill is so convenient. I'm impressed by the build quality of the ys640. It's so heavy. It won't be rusting through any time soon. No regrets. My treager owning buddy is buying a yoder as soon as his treager quits because he has grill envy

We purchased our wood pellet grill (Model TFB57CLB) from Costco in August 2017. It came with one bag of the gourmet blend pellets. We used the Traeger cookbook to try a few different recipes in the fall. Most of these involve a period of smoking followed by a period of grilling. The grill seemed to work fine at first. We used it a couple of times on warmer days in the winter and it had some trouble getting up to the desired heat level. We started using it regularly again in April 2018. I was careful to clean it and check the pellets etc. The smoking feature seemed to work alright, but when I would turn the heat up for grilling, the grill would usually struggle to get much over 225. I would resort to turning it up to 375 or more just to get it to 225 and then often it would sink back down to 180 or 160. I went to the troubleshooting guide on the manufacturer's website and checked all the components, which seemed to be working fine.

The Pit Boss really is the boss with its 700 square inches of cooking surface. The space alone isn’t what makes the Pit Boss 71700FB one of the best wood pellet smoker available. If you thought the Traeger TFB29LZA Junior Elite Grill had a lot of space at 300 square meters, then get more than double that with Pit Boss (the Rec Tec grill below beats it by only 2 inches).
An attractive option for many people are stainless steel pellet grills, which are rust-resistant, more durable, and easier to maintain. While pellet grills made from commercial-grade 304 stainless steel are the most desirable, they come at a higher. However, there are also some pellet grills made from 430 stainless steel, which is more affordable and still incredibly durable.

You are worried about flare-ups: When grilling fatty types of meat on a propane grill, you run the risk of having flare-ups, where the flame gets too high and too hot, burning the meat. You have to keep a close eye on the propane grill to guard against them. But with the Traeger grilling system, the even distribution of the heat and the indirect heating system prevent this problem.
One huge advantage with pellet smokers is that because of how they work, they’re all generally of a higher standard than a lot of other types of smoker. But just because you’re less likely to grab a bad model doesn’t mean that you don’t want the best, right? There’s still things to think about that make sure you get the absolute best fit for you and your family.
To cook food using a pellet grill, put the pellets into a hopper. When you turn it on, the igniting rod will burn pellets in the fire. The motor-driven auger will then supply the fire pot with pellets from the hopper. The ratio that auger delivers pellets to fire pot depends on the settings you control. If you set it at a high temperature for a longer period of time, the auger will keep on feeding the fire pot with pellets. However, if you are slow-cooking and set a low-temperature one, the feeding and delivery of pellets will also slow down.
I think a lot of reviewers here don't have enough experience in pellet grilling to recognize how many features are packed into this unit for the money. I'm not going to talk about the usual advantages of pellet grilling in general in this review (i.e., clean flavor, "set and forget", less ash,). Instead, I'm going to focus on what makes this one uniquely better than the other grills in it's class.
Brought it home and set it on my prep table with the controller in a cubby hole with all intentions of building a cart for it later. So I have made a killer rib eye on it and tried to burn it down with a couple rib eyes cooking at 600 F. Gotta figure out a little better method of catching drippings as they will catch on fire and you have a runaway! But you can make a great rib eye. Ribs, every set has turned out awesome, everything from low and slow to a high temp cook process on them. Probably made 8 racks of great ribs. Wasn’t impressed with the hamburgers on it but will try again later. Made a pretty good brisket but used Rudy’s rub as I like their store sandwiches and I don’t have the method down. Next one will be back to salt and a touch of pepper. Chicken thighs (thighs are the perfect chicken part for Q, their rather uniform thickness makes getting them all consistent and cooked even a slam dunk) with a light coat of mustard and Tony Chachere’s lightly sprinkled is to die for. Simply squeeze them when they should be close and if the juice is clear, no pink or red they are perfect. If you cook the juice out, well they make decent tasting blotter paper 🙁 Pretty much killed a spatchcocked turkey for Thanksgiving, good thing the wife made an over baked one too. It did make great gumbo though as does the blotter paper chicken if you ruin any thighs or the whatever chicken. Also have a pile of hot links I put on at 180 for 2 to 3 hours. They are great for reheat with sauerkraut and roasted pabs or in the gumbo. Hot links should be a staple, ha ha! Gotta try my great pulled pork on it and we do Prudhomme pizza sauce on a Brown Eyed Baker crust and this Pro should rock it!
For anyone thats thinking about getting this grill and this hung up on the price, you just need to take the plunge. And when you take it home you will realize it's worth every penny. And then after your first use, you will feel that you under payed. My first smoker grill was a green Mountain and there is just NO comparison on the market to the YS640. Grill grates and other add on's are amazing as well. LOOK NO FURTHER IF YOU WANT A GREAT GRILL/SMOKER/OVEN... ECT
Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
