Both M3 and I make pretty low cost systems.  Given the pressures involved, 
I do not suggest you design your own without the help of someone who knows 
pressurized gases well.  A good place to look for such a person is the 
place that sells you your regulator or tank.  Of course, pre-engineered 
systems have dealt with these issues already.  If you buy one of the 
European systems with unusual fittings on the tank, be sure you know how 
you are going to get the tank refilled.  The most viable non-standard tanks 
are probably the paint ball tanks, but I don't know if you can find an 
adaptor to permit attaching one to a standard pressure 
regulation/distribution system.  And paint ball gas isn't cheap by the 
ounce.  Remember regular old CO2 from a welding/beverage company is around 
$.07/ounce weight.
