The boat we're buying has a pressurized alcohol stove. Despite the fact it's in great condition (with a little cleanup, and I mean very little, it could probably almost pass for brand new), our surveyor recommended we replace it. He described the operational ins-and-outs of pressurized alcohol stoves--incl. their propensity for catching things on fire
. He recommended we replace it with an unpressurized alcohol stove that he said works like a Sterno can. (He mentioned a model name, but I can't recall it.)
What are these, how well do they work, and what do they cost?
