I really hope that you enjoy your induction range
Silit, WMF, Schulte-Ufer, Kuhn-Rikon, some Cuisinart lines, a line of stainless by Le Creuset and of course, All-Clad. Go to a Home Goods store with a magnet. I keep a small round magnet in the coin purse. For most pans, the ability to distribute heat across the bottom is not as important as with a conventional range because the heat is generated in the base of the pan and you don't have to worry as much about the thickness of the side walls as you do with cookware on a gas range because you don't have heat coming up the side. You should be careful of cast iron with induction because it will easily overheat and hold heat which sort of does away with the advantage of the induction repsonse. The other thing about cast iron is that it is less responsive on thermostatically-controlled elements and some induction units allow you to switch between power levels and temperature in Fahrenheit or centigrade, a feature that is very nice for deep frying. I use a nice 2.5 qt Cuisinart induction capable deep saucepan for deep frying onion rings and French Fries. I repeat, you do not need really heavy cookware, you just want cookware with strong magnetic attraction to the base. Quality stainless steel is what you want. Even porcelainized steel in saucepans works fine for most things.
When I cook frozen vegetables, I start the 1.5 qt. pan on the 3500 watt unit and the water with the frozen vegetables starts boiling in one minute.
