I just replaced my 24" GE oven with microwave attached with 27" inch double convection/microwave ovens. The old one was a 23 yr. old dinosaur. I only had 3 choices as to brands to fit in the tight cabinet. 3/4 inches along the sides of the cabinet had to be trimmed, but the ovens fit perfectly and even though they are larger ovens they look so much nicer with slimmer lines and large glass doors. I can now fit my large roaster pan!
If you go with a single oven, the cabinet can be easily modified with trim and moldings. The installer acted as it was no big deal and said he had to do it all the time. Good luck to you.
