I ran into the same thing when I got a 4500 psi tank in a trade. But I have been using the same scuba shop for several years and we are friends so I asked them about it, knowing that they maxed out at 3500 psi. So he said, "let me see what I can do." He opened and closed a few valves on his fill station manifold, hooked my tank up and turned his outside compressor on. A few minutes later, he had maxed his compressor out at 4000 pumping directly into my tank. Not 4500, but pretty nice. It also made me appreciate how important it is to build a rapport with the shops you frequent. It might be that one of the closer shops might be able to help you out like that. I am guessing you have already covered all the paintball resources, too?Lloyd-ss
Thanks for the tip.. Been looking at them for a few years now. what's wrong with the less expensive($549) chain driven model?
