Last time I checked, ebay had 20 oz. bottles for $17, which was the cheapest I could find. I don't know much about paintball bottles, but I'm assuming that there shouldn't be much difference between one brand or another.

Amazon is usually $20.

Craigslist is the best option if you don't mind getting a used one, in my area you see lots of paintball equipment up for sale very often. Just the other day I saw an ad for 5 20oz tanks at $10 each.

If you live close to a Dick's sporting goods and can't wait on the mail, they have them. PB stores also.

If you are buying used make sure to check the hydro-test date. If the hydro-test date is expired you won't be able to fill it up at a retail location.

check craigslist first then amazon or ebay I got my two tanks on amazon

I would opt for new ones if I were you, you never know what someone's done with a used one.

I've bought mine on ebay, amazon, and at Academy sporting goods. I would recommend buying at least two, so you can immediately swap out when you're empty. I've got paintball CO2 on 3 aquariums so I have 6 tanks.

I purchased 3 3skull 20oz tanks for 42.00 delivered. 5 year hydro. Just have to watch for deals.
