Kathleen,
I have a Sharp Carousel Microwave Convection Over-the-Counter oven and I love it! I use the microwave more, but I love have the convection oven too. Just tonight I wanted to make twice baked potatoes, but it is so hot (over 100 today in Southern California) I didn't want to heat up the house using my oven. The convection works great, but it does cook things a little faster than a regular oven. I am glad I spent the extra money to have a duel purpose extra oven (especially during the holidays). My model # is R-1870F and it's 850 watts. I've had it for about 3 years and no problems.
