Cheapest way is a beercan pot, as many have mentioned. Wal-mart grease pot is good
too and more durable, although by the time I'm considering 5 bucks for that, I just spend
10 for the Anti Gravity Gear pot since you don't have to mess with the lip like on the grease pot. (I carry the
AGG pot most of the time. I've used a canpot, but I find I'm a little too tough on them
and tend to crush 'em.
