I think you'd need a valve, with a pressure gauge on it (same thing you see on Oxy/Acetaline welding set ups, and air hose. I think thats about it (plus your attachments for the hose but thats kinda up to you)
Check out The Source. I got my regulator/hose/chuck/mounting bracket from them.
Don't bother with a regulator with gauges...they don't register that the tank's empty until it's, well, empty. CO2 is in liquid form and simply evaporates as you use it. The gauges won't show pressure change until there's only CO2 in gas form left in the tank.
Thanks for the link Ryan above Ryan. I'm going to order that up. I pieced together what I would need at a couple of sites and they all came up 20-40 more expensive. This should work fine!!!! It's GHETTOFABULOUS baby!!!!
