When we talk of 'canister' stoves, it's safely assumed we mean iso-butane in threaded Lindal-valve canisters:
Here in Parts Unknown I've seen butane packaged in aerosol cylinders with twist-click connections
In the USA these are used in car camping (NTTAWWT!) stoves
although in Japan and other locales they make nifty hiking/cycletouring stoves that use the twist click cylinders
My local Walmart, Acadamy and REI have a shelf full of these aerosol butane canisters, but I haven't seen them
anywhere in the hinterland.
There are Lindal-to-Aerosol and Aerosol-to-Lindal adapters available.
