My neighbor has a Traeger and absolutely LOVES it. He's a bit of a chef so I trust his judgement about equipment, cooking methods, and food quality. But every time I tried to check one out, at CostCo, or the mall displays, or wherever, I just couldn't get over the thinness of the metal and the grates inside. So in the end I kept using my stickburners until Traeger's patents expired and other companies joined the fray using thicker materials. Ended up with a Mak 1-star, which I love.
I fully acknowledge that with the electronics, etc., maybe thickness or substantiality doesn't really matter for a pellet smoker. And the Traegers may be fantastic pellet smokers, even better than my Mak. Maybe I really missed out on pellet convenience for years. But I know myself well enough to know that every time I fired it up or used it, every time I walked out and saw it, every time I touched it or lifted the lid, the thinness and lightness would make me feel bad.
Maybe it comes from using quality stickburners for 25+ years, but at least IMHO there is a tactile aspect to smoking and grilling with quality equipment -- not necessarily expensive, but quality -- that is inextricably intertwined with how I experience and enjoy the process.
