OK, Old thread. Update though, the Sharp would never come up to temp on preheat, no apparent way to calibrate, you can just use a higher number to get to where you want, but that was a pain.
We bought the Whirlpool cone/micro and installed it yesterday. Works great. The Sharp will be sold as microwave with a sort of convection.
The comments about the Advantium, well, forgot about those, but had helped Forum member Chet install his last spring, and they love it, so I went with it and it was on sale.
