I have the 30" Bosch cooktop.
http://www.us-appliance.com/nibo30fuin4b.html I love, love, love it! My only regret is not getting the 36". I replaced a Jenn-Air 30" downdraft that was about 20 years old. I did have to replace almost all my cookware. I have found that cast iron is one of the best materials to work with induction. Old technology meets new technology. I also bought a portable induction hob to try out the technology before committing to the cooktop. The portable is not as powerful as the full size cooktop and it is louder. You have to listen to hear the Bosch fan come on. It is very easy to clean. You do have to try out cookware to see not only what works, carry a magnet with you when you shop, but what will be noisy. My mom gave me some waterless cookware that is very nice, shiny, pretty and magnetic but I can't stand the sound of vibration it makes. If I can give you any more information just PM me.
