Marvin-
Can you give us a cannister type or model number?
The stove is probably made over there in the Orient (isn't everything, though), but has not been modified for U.S. / Canada available type canisters. Probably available at Oriental Markets because some are brought over by immigrants or ordered online by them from there.
I remember reading about one of the types of canisters being available at Oriental markets.
Is it this one?

From the source I revered to in the earlier post:
"There are several companies that make butane cartridges for portable stoves. One such design has a bayonet male fitting and a collar with a notch in it. These canister may cost a little less than their wider based brothers and may be easier to pack. You may be able to find these canisters at boat shops for a price or at Asian markets for very very cheap."
