Where can you find an induction cooker for $100? I have an induction
plug-in for my JennAir, and I really like the "cooking with gas"
qualities of the device. It would be nice to have a moveable unit.

Please log in for more thread options What is an "induction cooker" and where can you buy one for $100?
Recently, the guy at the auto repair shop I go to showed me a little
induction heater that has a heating coil on the end of screwdriver-like
handle. You lay the coil over a siezed-up nut, pull the trigger, the
nut turns red and you take it off. Car doesn't catch fire, knuckles
aren't bruised, etc.. I have no idea how much the thing cost, but it
wouldn't be too hard to find out.
In general, induction heating devices that I have seen aren't all that
cheap. So, if you do have access to that $100 device, I'd sure like to
know where I could get one.

An induction cooker uses induction to heat the pot/frying pan. They
are very efficient, compared to electric ranges.
I was just thinking that one of those would make a cheap source for
the control electronics and the coils look flexible enough to reshape/
reuse from the one response showing somebody taking one apart.
