I have owned 3 Traeger grills. Little Tex, Texas and my currant model the XL. I never have owned or operated any other pellet grill. My question is how much better a high end grill is than my Traeger. I'm talking Memphis Elite, FEC or Mak 3 Star. Im talking double wall stainless steel. Anyone have one of these? I know about others in similar (better in some ways) price ranges to Traeger. I am specificly looking for the top end here. I realize these can cost 4 to 6 grand. Thanks for any thoughts.
