We bought a profesional induction plate, 4.5kW, 100$ on ebay. Performance wise, its ~4x better than the 4kW gas stove it replaced. The time required to heat 50L of water to 60C went down from 60min with gas to about 10-15 min with induction.
Instantaneously hot, and instantaneously cold. For us it opened a lot of new ways of cooking.
What kind of cooking do you prefer doing on a gas stove over an induction stove?
Obviously the same pots and pans don't work on both, but if you have a top of the line induction stove you know this already.
