In our last kitchen we had a 30" Bosch gas cooktop. We loved the gas, and swore that we would never have anything else. We do a lot of cooking at our house, and the two things that we didn't like about our Bosch were having to remove the grills to clean up after a night of cooking, and the 30" size. When we heard about induction cooktops, it seemed too good to be true. They are way more energy efficient than both gas and traditional electric, they have temperature control as good or better than a gas cooktop, and the glass top makes them easy to clean. The one downside is they are expensive. Our Bosch put us back $600, while the 36" Gaggenau we chose for this kitchen cost a shocking $2400. It was the one big splurge for our kitchen and I think it was worth it. There are quite a few induction cooktops out there, but to me what sets the Gaggenau apart from the others is the removable puck. The big dial used to control the temperature just sits on top of the glass and stays in place by a magnet. Burners are selected by sliding the dial in their direction, and then twisting to get the temperature you want. I love the tactile feedback of turning a dial compared to a touch control for the temperature, and the fact that it just sits on the surface means it's simple to remove for cleaning.

Check your local Gaggenau dealer for pricing (we got our for just over $2400)
