Here are my comments. Miele Combi Steam/Convection Oven - great choice. I would stay away from ANYTHING Thermador makes - expensive to repair, frequent repairs and poor customer service. I don't have experience with Electrolux, but the micro/oven combo I like is the GE Profile Advantium upper with a 30" convection lower (Combo is about $4,000). That Advantium oven does a MUCH better job than a regular microwave. Would not buy Viking, period, for the same reasons as Thermidor above. Viking took over the old Amana refrigerator plant. They are a great marketing company, but a poor product and service company. I'd suggest a KitchenAid 22CF panel-ready French-door cabinet depth R/F or possibly a GE Profile similar model if you're not going to put in a built-in refrigerator (SubZ et al). Miele dishwashers are great as are Bosch and KitchenAid, who now have the same type of filter system as Miele and Bosch do (they got rid of the built-in garbage disposals which make dishwashers much noisier). BlueStar Rangetop is fine. Personally I like Capital Culinarian - 25K Btu on 5 of the 6 burners and I think a 12K Btu simmer burner. Getting back to your oven situation, i'm in a remodel now where I'm putting in a 6-burner Capital Culinarian all-gas range with a Miele XXL Combi-Steam oven. No need for a 30" convection wall oven or a built-in microwave. Our microwave (which we just use to reheat beverages primarily) will be an under cabinet GE Profile model (cheap - $350). the Combi-Steam oven does a much better job of re-heating leftovers than microwaves do and it's great for steaming, roasting, baking bread, etc.

Is KA's "steam assist" the same as Maytag's "Aqua lift"? If it is, beware. There have been complaints about the ineffectiveness of that technology. See link below. OTOH, it may be a system that will work for you and the way you use your oven. Just something to consider. Here is a link that might be useful: Aqualift problem

I'll second joeb's opinion. Weren't too sure of Therm ME at first, but when compared with everything else on the market - it came in with the best overall deal as far as cubic size, bells & whistles, pre-heat, and full backing of app. store (in writing), so we went for it. There have been some concerns, but believe a lot of issues have been resolved. Got an xtended warr just in case. Considered KA - really liked the looks, but frankly, repair issues & customer service have been really iffy for quite some time, so we opted for Therm instead.

This has been discussed before. While my CSO is by far my favorite thing in my kitchen, it is not a substitute for a regular oven. I would encourage you to keep an eagle eye out for a good deal on a basic wall oven from Bosch, of KA, maybe even Frigidaire. You will not regret splurging on this appliance, but it small and a regular oven will be absolutely expected for resale (which would be hard to add as a pst minute thing considering the cabinetry, etc.)
