When mine went south, I wanted to replace it with a convection, but where I was at I couldn't find one to fit the opening, Just got a regular one at Target. I got four of the rubber feet that fit over chair legs and cut them short.I then ran a short screw through the center of into the surface it sits on, each spaced so the legs of the micro fit over them. Works well and I put back the plastic trim so it looks like it belongs.:D
