I am reviewing the purchase of a new dual fuel range and would like advice on the pros and cons of two models I rec'd great prices on: 1) Thermador (304 us - old model closeout) - 30" dual fuel w/ star burners; I wonder about the star burners andif there is an advantage to them; also is the oven big enough for normal baking sheets? how is the broiler? 2) Kitchen aid pro series 30" dual fuel -- has anyone used this model -- Ithink it's fairly new on the market and wondered about it's performance for in-home use -- it's got a nice price, but I wasn't sure about reliability; but it has some nice features (eg. easy to clean cooktop and high btu burners and some handy things like time bake and a hidden heat element in the oven any advice would be fantastic! i do lots of baking and stove top cooking, so I need the advice of all you great semi pro home chefs!
