CO2 Tank, Regulator?

[DrowningTrout]

My cannon Im working on is going to be powered by CO2 (20oz Paintball Tank). Im trying to figure out how to pressurize my chamber with CO2.

I was thinking about using a Kobalt CO2 System:

But $85 is a little pricey... Is there a cheaper/better way to do this?

Thank You!

Sorry for all the noob questions!

expansion chamber then fill from there?

or a really high pressure gun

but if you had a largish chamber you could fill from 12g c02 canisters

If your putting out 85 bucks go with a better reg like the palmer stabilizer. Or if one of your friends plays paintball ask him to ask around if anyones got a used one to sell.

A co2 setup is probably going to be a little pricey, a 12 gram co2 filler is a cheap way to go, but if you use a lot of them, it gets more expensive.

I wonder about those kobalt regulators, they are compatible with 9 and 20 ounce bottles from lowes, but could they accept regular paint ball tanks?

Yea, Im pretty sure they are just paintball tanks...

Im looking for rapid fire rates, so I don't think the 12 gram co2 will cut it.

So anyone give me a link to a cheap/better alternative?
