I was SO excited when I was finally able to get a new oven. I had to have a convection, though I'd never had one before! Turns out, I rarely use it unless I am using more than one rack in the oven. I bought one of the larger ovens, and because of the fan for the convection usage, my big cookie sheet will NOT fit correctly. I am not happy about that-something to think about! My SIL has one and uses hers all the time and loves it-part of the reason I thought I would like one. Honestly, I would trade the convection for more room in the oven. LOVE my glass top though!
