Re the handy tubes, if you know someone who smokes cigars, or have a smoke shop handy, you can probably bum a few for nothing. That is how I obtained the ones I have. Be advised that the top is not real tight, probably not waterproof (altho I have never tested that), and comes off pretty easily (unless you seal it with tape or something). If you can get the aluminum ones, they have a threaded cap, mucho better...
