To save money, would it be a good idea to purchase one of the air tanks that are advertised on pbnation (not sure what brand, but they are going for $109) and then just slap a ninja pro reg on there? Still coming out much lower then any other new tank.
thyel et you pick what reg but a ninja pro adds 30 on to cost
not true on ANS GAS bottles. Look at the section that says Choose Your Regulator. The only one listed is Crossfire. The Ninja line of regulators is not offered as an upgrade on that bottle unless you buy the bottle with regulator and then buy a Ninja regulator as well.
