At one time I had 30 some back pack stoves I sold a few and gave some to youngin's just getting into camping . I have now the optimus stoves listed above svea 123, 8r,99, 111 hiker, a small coleman that will burn kerosene by changing the generator, A coleman propane that the cylinder sets to the side msr dragonfly, and pocket rocket, one of the little folding wood stoves, a brasslite I have a sterno stove kit from the 50's that will cook and a trangia 27 and a trangia hotplate
If I'm out woods roamin' and just need tea or to heat lunch the pocket rocket goes .. Camping I use the tragia 27 or the 8r the most
Those surplus swedish stoves are hard to beat if your on a tight budget
