All joking aside Lucifer, the standard air systems in this country are:
3000 psi
4500 psi
as a newcomer to air, i would stick to something straight forward like a preset air system, that screws into your existing asa.
Are you using it for rec-ball or at tourneys, as you have to be able to get it filled at least once during the day.
CO2 would be the easiest way to go, and the cheapest, if your rec-balling, but air has many more advantages over co2.
Overall air is the better, but co2 is cheaper.
