Thanx Todd. I spoke to my local Pub owner the other night about the CO2 tap setups. He said that if I want to save some money and get a bigger tank, I should talk to a soda distibutor and give them a deposit on a tank 10 or 20lb tank, the deposit is like $20 and the tank belongs to them, but you can buy it if you like. Its kind of a short term solution, but I thought it was pretty cool that I could buy the regulator, air hose and get the tank for under $70 ($40 regulator, $20 deposit on the tank, $10 air hose), instead of spending $100 on just a tank. The soda vendors also sell used tanks, regulators, etc. And if that still isnt cheap enough in Sunday's Paper they have auctions for Bar equipment from bars that went out of business. You could probably get a whole setup for next to nothing. I just can't justify $300 for a powertank setup. And I will not cut corners on safety issues.
