Look at the review on Amazon.com, it's not pretty.
I decide to go with a paintball system. I did a lot reading, and gave up the idea of a DIY system (considering the high pressure involved, just to be safe). One option is a "regular" CO2 regulator with a paintball adapter, but didn't really find anything that appealed to me, then I found this one:
AQUATEK CO2 Regulator Mini with Integrated Solenoid for Paintball Tank (R-78)
I will probably buy this one in the next few days. The reviews on Amazon.com look good, too. It's just sad that amazon.ca doesn't have it. It's about $90 US on amazon.com, and it doesn't take up much space.
Any comment from guys here?
Also, where is the place to buy a paintball cylinder or have one refilled, in GTA?
