If you're going through a bunch, why not refill 'em?

They sell adapters like this: http://www.mrheater.com/sporting/propane-tank-refill-adapter-1385.html that allow you to recharge them from a standard tank. Won't fill them completely , but carrying two small half-full bottles has to be easier than carrying a big 20-lber in some fishing circumstances, and it's got to save money in the longer run.

Ebay has lots of options: http://www.ebay.com/bhp/propane-refill-adapter

So Retro, can you take your little bottles anywhere with this adapter and they'll fill them? Like at Cosco, for example? Or is it a matter of hooking it up to your big propane tank and filling them up that way?

When I was a rescue diver with a volunteer fire department, we used to refill our own scuba tanks. We used what was called a cascade trailer in which were about ten big long pressurized air tanks. We'd hook up our scuba tank to the first one and fill it as much as the first tank could fill it, then move to the next one, and so on until you had it filled. The idea being that the fuller each big tank was, the more could be pushed into the smaller tank. If you had several bigger full tanks, you could go from one to the next until you had your smaller bottles filled. I like iFish's idea about putting them in the freezer first, because they get hot! we used to have them submerged in a side tank of water as we filled them to help cool them down,
