If money isn't the main deciding factor, you should definitely look at the Wolf Dual-Fuel Range. It is the best on the market in my opinion currently. The Viking is also worth a look... less electronics, less to go wrong.

The Kitchenaid looks good from afar, but you should definitely go see each in person. There is a definite difference between the KA and the Wolf, as well as a definite difference in price.

Hope that helps,

KA makes great DWs and fridges (that's what I have) but their cooking appliances particularly the ovens have had issues. Instead of dual fuel, consider an all gas range - Bluestar, Capital, Wolf, DCS are all good choices - and a lot cheaper than dual fuel ranges.
