I have 2-80 cu. ft, 3500 psi, Scuba tanks, which I obtained from my local dive shop. He also fills tanks for the paintball crowd, and these are 2 tanks marked ' paintball only'. I bought the hose assembly from Joe Brancato at 'airtanksforsale.com', who has every type of hose assembly/fitting you can imagine for using tanks to fill the Marauder. Compressed air from the dive shop is filtered and dried, so that you won't be getting condensation in the air reservoir when you fill it. It is, therefore, the best to use.
CO2 is a pain to use, because it changes from a liquid in your reservoir to a gas, which then powers the gun. This state change from liquid to gas means that the pressure will change from shot to shot, and will be affected by the temperature of the air chamber and the outside air.
The N2 setup from the welders supply is way too expensive and way too heavy to be able to take with you when you go to shoot targets or hunting. The full size N2 tank was quoted to me as weighing several hundred pounds and is too big to fit in my car. That's out.
I believe a 'piglet' is a name for a AL/carbon fiber tank, from whom I don't know.
