On Topic? What ??? Go figure ...
The state of microwave overs is tragic with the market begin taken over by 3C (Cheap Chinese Crap) manufacturers: they last a year, flame out, start on their own, etc. etc. etc..
I finally found a microwave I absolutely adore. It only have one optoelectric rotor knob. And it has no turntable. It have some kind of scattering technology that cooks more evenly than a turntable. And it is easy to clean. Built like a tank. I expect to outlive it. It is twice as heavy as a 3C model. It is really, really easy to operate! It is quiet too.
Guess what, it is the same microwave you find operating at 7-11

Cost comparison, not including fire damage, fire extinguishers, switched electrical outlets, wear on ones nerves, etc.:

By the way, it is not made by Toshiba. Some 3C manufacturer bought the rights to sell it under Toshiba's name.
Cost of Ownership:

The Sharp is made in Thailand, not China.
