Hey all,
I've been looking into pressurised CO2, and MAY have found a way to get a system set up as cheap as $80. ($105 if you incl the solenoid.)
Paint ball cylinder, 12oz: $35 from Paintballstuff.co.nz
Found a regulator on eBay that SHOULD work, (but I would love some feedback on this): $23.99 USD
Found a 3 in 1 diffuser, bubble counter, and check valve. $10.76 USD
Found a solenoid, but this is a night time turn off thing, I think... $21.29 USD
I would love some feedback from those who are more familiar with CO2 set ups.
