thank you for the reply!!

i had a feeling this wasnt really a common thing, i searched quite a bit, and figured if i couldnt find one, then it probably didnt exhist....

i dont mind buying MSR or Jetboil canisters.... i DO however have access to a whole bunch of the coleman propane ones (freebies from a relative).... i was just looking for more flexibilty from my ultralight MSR stove....

i guess ill just breakdown and buy one of the cheap coleman propane stoves, see how it works with my one-nighters.... im not so much concerned with the weight for short trips.... i am curious to see how long one of the propane cylinders will last me....

thanks again for the reply....
