The Nitro Bottles the paintball stores use are Bulk Fill but they come full at 4500 psi. MOST Welding Gas Suppliers carry them and will DELIVER them at least to your local welder on a regular basis. They usually want a REFUNDABLE Deposit for the bottle. Refils, a bottle swap, is CHEAP! The only wrinkle is the regulator. Those can be a couple hundred dollars. But you don't NEED one IF you don't try to fill your tank past 3000 psi. ONE SAFE way to do this is to get a 0-5,000 psi guage. Just vent the N2 down to 3000 psi before you try to fill anything. Then you can just equalize the two tanks when you fill with safety. All you need is a your fill hose, tank fill fitting, a T fitting, the guage, and a plug for the fitting so you can pressurize and read the guage to be 3000 or lower. All the fittings and hoses have to be rated 4500 or higher.
