Hi,
We have an induction stovetop and we LOVE IT. I grew up with a gas stovetop, and I have to say that I now prefer induction over even gas. Works so quick and well, is safe, easy to use, easy to clean, etc. I love that when I'm finished with cooking something, I can just slide the pan over to another 'burner' and the stove turns itself off. I love that it takes about 30 seconds to boil my water for oatmeal. It boils water faster than the microwave. I love it so much.
Okay, you're already sold on it, so I will stop.
We use a mix of All-Clad and . . . ooh, I can't remember the other brand we use, but I'll check when I get home. It is a cheaper brand, either calphalon or cuisinart, but I don't remember...
I don't have a cast iron pan so I'm not sure if that works on it.
One note on the All-Clad--we use the "regular" All-Clad that we got as wedding gifts 15 years ago. I had one All-Clad saucepan that was the brushed stainless, I think, and it did not work on the induction, so I gave it to a friend.
You can also buy a "converter" type thing (not sure what it's really called), which looks like a flat pan that you can put on the induction range and then put a "regular" pan on top of. We find it easier to use the pans that work directly on the induction range, so we didn't bother, but that's an option if you want to try that.
