As an experiment, I bought a Max Burton Delux 6200 1800-watt portable model (110V) about 3 years ago (from amazon, around $80 at the time). I love it. It boils water in my kettle much faster than our 220V electric-coil stove burner, and even marginally faster than a propane burner we used in the past. The heat is nice and even (though also a function of the pan itself -- our induction-ready pans are a notch nicer than our older pans) and turning it off means instant heat reduction. I've had far fewer incidents of burning or scorching with the induction unit.

Highly recommended.
