I replaced my double ovens a year ago when the original one died. I bought a mid-range GE model, in white. The top is a full size regular/convection oven and the bottom is a full size regular oven only.
Mine are built in to a cabinet as well. I was able to buy a standard size, though. I like them fine - rarely use them both at the same time and only occasionally use the convection part.
What I really wanted was the model with the French doors instead of the standard pull down, but they were much more expensive. Maybe next time...
