credit for this goes to almightydolla for origionally making this unit.

pros

cheap
cheap
small
anybody can do it.
cons/problems:
12 gram co2 may not last very long
the needle valve, i found out after i bought it, is only rated up to 150psi. so for fine adjustments, its just about worthless. it either runs really fast or really slow gas flow. here is a link to some of the different needle valves for brass fittings and it needs to be rated for NPT(national pipe thread) http://www.google.com/products?q=brass+needle+valve&hl=en&aq=f
