I own a Memphis and wouldn't trade it for anything. They are insulated(double wall) and made from high quality stainless steel. The Memphis has one of the lowest pellet consumption ratings of any pellet grill. That means that using less pellets per cook saves you money. The more expensive pellets cost you the more you save.
Mine has a temp range of 150F to 600F so it can go low and slow or grill like a champ. The insulation helps it hit grilling temps with ease!
There is a short throw auger and a front loading hopper. The igniter is not located in the firepot. It is just outside of the firepot so it is not exposed as directly to soot and ash as other grills. Also I have never had a burn back through my auger because the pellets are ejected and slide down into the burn pot from a chute. The multi speed fan blows air into the burn pot directly. At lower temps the fire is bellowed occasionally to regulate temps, stimulate smoke, and reduce pellet consumption greatly while keeping temps with a degree or two. Crank her up and that fan wakes up the flame and the short throw auger dumps pellets like a champ for grilling temps.
The new models are coming out this year with totally new controllers that have several probes built-in and wifi control.
And they are made in Minnesota. Just putting mine together when I bought it I was amazed at how well they are made. And they are just a beautiful looking grill... Well if your into that
To me a Memphis is worth every penny.
