I, like MTPIZZA, had one of these types of ovens - It was branded as PIZZA BELLA - great little oven, little being the operative word. I think mine did a 10" pie
+.
When it finally broke after a few years of service I took the 1/8" thick stone out of it before I set it on the curb for disposal. I still use that little stone on a gas grill rack when I want to make a small pizza at our lake house. I think I paid $59 USD + some shipping and thought it worth the money.
Neat little unit - just small
