Just purchased my first PCP gun, and compressor..... now looking for a good, usable 4500 psi air tank. Doesn't have to look good, just be solid and dependable. Would prefer at least a 30 cut ft, but would consider smaller if the price is right. Looking for something that I can carry with me, or at least onboard my ATV/4-Wheeler. As a Bladesmith, I'd be willing to do a trade for one of my knives. (you can find my website/knives here: http://www.caffreyknives.net/)
