I found one while browsing the camping section last night at Wal-mart. It uses coleman liquid fuel and unleaded gas. The liquid fuel is supposed to be wayyy more efficient than propane, but I'm wondering if I could use alcohol in it. I have tried on numerous occasions to make a soda can stove, only to end up spliting the top can when pressing them together. The Coleman stove is near $40, kind of expensive to experiment with. What are your thoughts?
