I own three Traeger pellet grills... a PTG, a Junior, and a Texas. Do I like them? Not as much as my Fast Eddy PG500, but they work...
I would not really recommend the PTG to anyone... I got mine used cheap , and never really expected much out of it. It's prone to auger tube fires and can barely cook a half a chicken on it... I bought it , with the intention on turning it into a smoke source for another device.
The Traeger Junior can produce some good food, but it's got big temperature swings. It was my primary pellet grill for about 4 years and served me well. Still would have a hard time recommending it to anyone.
The Texas , I bought used... used it once or twice... it works fine, up to about 450F. I don't like the shape much, not enough headroom, and generally too big for 90% of the stuff I cook.
Timberline grills look interesting, but they are quite pricey and will only be in limited supply... I doubt that I would ever own a Timberline, mostly because I have a Fast Eddy PG500 that does about 100% of what I want to do on a pellet grill.
