@KGsPFT - Aquatek makes a newer "mini" regulator that's for paintball tanks (no adapter needed). Their older full sized regulator has been out for sometime now. It has a great track record and cost less than the Milwaukee. Milwaukee is good too, but you get more for your money and plus all the extras included (co2 tubing and bubble counter w/ check valve) by getting the Aquatek. I'd link it, but TPT removes the ebay links.. Just go to ebay and search Aquatek. When it was on Amazon (which it usually is), you can read the reviews there as well. Seems like a well constructed regulator IMO.
