On the cooktop, I understand your attraction to the finish, it is lovely. But make sure you consider function first. The GE, as far as I remember, requires 12" of clearance underneath it, so you can't have a shallow utensil drawer as many of us do - that may not be important to you, but you should be aware in case it is in your plans. Also consider the hob placement. Some like the big hob in front so it's easy to saute, some prefer in back so you don't have to reach over big boiling pots. I don't know how the GE is set up, but think about what you would like. Finally, make sure the controls work well for you. Some you have to tap repeatedly, some you slide your finger along. Some people like timers. You may have already thought of all this, but I thought I'd mention it in case you hadn't.

I think the GE oven you're thinking of may be the Advantium speed oven, which combines oven and microwave. I think Miele makes one, too. In ovens, many of us like the Electrolux non-Icon Wavetouch as a good mid-priced unit. It has a "Rapid Preheat" setting. But you might want the look of the smaller oven to coordinate with the one right beneath it. You also might want to think about the color of the displays if the ovens will be "glowing" all the time. A red clock on one and a blue clock on the other right below it would probably bother me.

If you search in google something like "gardenweb advantium" or "gardenweb wall ovens" or "gardenweb all refigerator" you'll find old threads. It's much better than the search function right on GW.
