Cheap c02 setup

[1nxtmonster]

Does atone know how to reg down c02 (paintball or 12 gram) for under $100? I saw palmer-pursuit had a 12 gram cart regulator, but are there any regulators that go directly on a c02 tank and can reg down to about 100 psi?

I was thinking about a co2 setup, but it would be expensive. A stirrup pump or a fridge compressor and some air tanks would be best in my opinion. I would forget about CO2. Its a lot of cash. But for it, I would get a 12g co2 adapter, buy the 12g co2s in bulk, and a palmer stabilizer.
I'm assuming you'd use it something like a paintball or airsoft game?

Yeah, it's for my airsoft gun that I'm building.
