I’ve ended up with this beast of a pellet grill, which is far more than I intended to buy. It is of stainless steel construction, double walled so as to retain heat. It is capable of temperatures from low to 600°F which is much higher than my Traeger would go.
I bought my old Traeger Pellet Grill in 2011, and it has done me well. Even after the controller stopped working, a few years ago, I managed to safely rewire it with a simple relay and timer mechanism, and retain much of its function. But I knew I would eventually replace it with a new grill.
