Ahh that makes sense! For what it's worth, the cooktop we're using was $200. It is a bit rubbish: coil whine and the temp control is pretty coarse, but serviceable. I haven't looked, but I'd guess there's a sensible middle ground somewhere in between!

To be fair, a high end built-in induction range for four pans can easily cost $6k or more.

www.njori.com is a currently-vaporware device that looks potentially even better than the Control Freak and is substantially less expensive.
