We've had this for about 3 months and it was purchased with other cafe appliances for our new build.  This is by far, hands down, my favorite appliance.  It is expensive, but we didn't want a stack oven, nor a 48" oven, so we purchased a 36" gas range and the speed oven.  This speed oven is perfect.  It is a microwave, proofs dough, bakes a casserole, gets a pizza crust crunchy and broils.  You have to swap out a glass round spinning tray for the microwave function with a metal tray for the oven functions, but we made room in the cabinet above the unit for the accessories.
