I am considering purchasing a pellet grill. I want to use it as a smoker, but also want the option to cook at higher temps for steaks and burgers. I want a dependable pellet grill with a good hopper and auger that will hold temperature, is well sealed to hold smoke and heat, and is made with quality material that will not rust out, For those of you that have a pellet grill, what are your recommendations for brand and model that best meet my preferences? While cost is a consideration, I am willing to pay more if it translates to better quality.
