I bought a Campbell Hausfeld 2 stage off Craigslist for $100. The pump had seized up. It was old! Had an 80 gallon tank and a 3 phase motor. Anyway, I found a CH dealer who wanted to buy the pump from me for $600!! They rebuild them and sell them for $1,200.

I just bought a set of reed valves ($200), a new check valve ($30), and a variable frequency drive for the motor ($200). That sucker puts out more air than I'll ever use.

Point is, look on Craigslist for a quality unit. If you're willing to do some work, you can get a huge amount of air for cheap. The tank on that thing has an ASME code stamp!
