I’m by not stretch a cookware enthusiasts. But everything except one piece I bought over the past five years supported induction without me paying any attention to it whatsoever. As far as costs are concerned, I have no clue. Since I am not in the US, basically every home here in Germany has the electric wiring required for an induction stove.
