I am looking to buy a small camping stove for touring, however I am not sure what to buy, I have been looking at a propane stove, but most the stoves seem to use isobutane, and I would not know where to get canisters for that while I am on a long tour. I know up here Propane canasters can be found at any Wal-Mart, isobutane though I am not to sure about.
