I'll ditto the suggestion for induction cooktop. That's what's going in my boat and we're planning to do the galley makeover this year - that's going to be a biggie! How much do you want to spend? Fagor makes decent induction cooktops. Summit makes them too, and they are probably the cheapest in terms of price, but many people complain that "low" isn't low enough. If you choose radiant heat instead, you should be able to find one almost anywhere such as Home Depot, Lowes, etc. at a lot less cost of induction.
