I have some of the surplus messkit stove sets. The main thing is that the plastic container for the alcohol does not take well to overheating/freezing (in truck toolbox). Went camping this last week and decided to make sure that I had enough fuel. Both bottles were empty, so I filled up before leaving. Next day, got ready to make coffee and found that the flask was leaking badly from a stress crack. Didn't lose too much fuel but I decided to get a staineless flask for next time.
