(quote) ok,a good friend of mine which is a very new to the sport thought co2 tanks[with valves etc] thought that once u use all the co2 out of it u throw them away,he said he spent about 135.00 on co2 tanks[my field sells them for 20.00 each filled].im posting here to make sure no one else makes his mistake.

Ok, so it would be really tempting to make fun of this guy's friend. Count to ten, take a big breath and say to yourself, "Newbies are good, newbies are cool, newbies are the future of paintball"!

Play ball!
