For comparison, in Australia, gas and induction are at price parity (a budget 4-hotplate setup costs about $200-300 either way). You can buy a single-plate induction cooker for $50 that plugs into the wall and has a temperature configurable from 60-200 C.

PS: Also, electricity is cheaper than gas in Australia, because we have so much rooftop solar, electricity is soon going to be free during the midday peak.
