I have the least expensive Kenmore and it is not making me happy. It replaced a top of the line GE (from 1993). Burners are too hot, oven isn't well insulated, burner rings deteriorate quickly. I do have the oven clean cycle. I wouldn't be w/o it. No convection. My convection microwave wasn't impressive, though I did use it for overflow on Thanksgiving and Christmas. My sour cream cookies would not bake properly in the convection oven at church.
