I have a 4 rack gas burner from Lowes that I've had for 4 or 5 years. It has served me well.
My opinion...
Personally I believe that most of us are not proficient enough at PREPARING THE MEAT that the smoker itself is not THE key to the whole scenario. Meat half ass injected/prepared and smoked on a Traeger will not turn out near as good as as well prepared meat smoked on the $60 Brinkman electric that we have at hunting camp.YMMV
