First off I would like to say I own 3 pellet grills, 1 woodmaster, 1 treager lil tex and 1 treager texas. Love them all, cooked on almost all brands! I have seen Yoders operation and they do make a very good unit. Just finished it late and just after I bought my last treager,
I am not sold on treager but it was more for testing and beating up. I have 4 people that beta test pellets for me when we do new things or just want to test batches of them. Their is a Green Mountain and an FE plus a MAK and a Louisiana Grill in that mix.
These are just like carts...some are better than others and you will pay for it. Some hold temps great other have a bit of fluctuation. I like the fluctuation...seems to smoke better...but thats me.
What do you want to buy ?? a Rolls Royce or Impala?
Pellets... that is another thing. Some manufactures like treager put in about 30% or so of what they say is on the bag and use either oak or alder to finish it off. Leaving alot of people thinking the pellet grill does not impart good smoke when it was a pellet issue all along. Some pellet manufactures do not use any oak or alder. Which brings out a better smoke profile.
Some pellets will not get you over 400-450 due to not having any oak or alser to get the higher temps but, they will deliver great smoke flavor.
All in all ... read ask read, try one if you can or find someone with one.
Test different pellets to see what you like. Some are great some are not but, unless you try you will not know.
Merry Christmas and Happy Smoking!
