I don't get it. I'm never going to abandon my little green cans... seriously. I toss a few of them in a plastic case on the roof rack along with other cooking items for trips, another 1 or 2 are always in the drawer, I've been running the same dozen or so in circulation now for at least 4-5 years, just refilling them. All my stoves use the little green cans, if I allow them to fill overnight they're as full as they were new, and for about $1/can. Plus I don't have another project to do before heading out, same reason I don't like CO2 tanks, and won't run one of those again. Only thing I can't do is run a fireplace for more than an hour or so without swapping tanks... usually that's more than enough. change my mind!
