I looked at the offerings at Lowes, Home Depot, Northern Tools, etc. I wasn't satisfied with the offerings and did some research and came up with what I think is a very good deal on a very, very powerful compressor. North Central Air in Downs, Kansas sells Industrial Gold Compressors and Leeson Industrial Motors. To make it short, I got a
42 CFM dual stage, 4 cylinder, with unloaders and all that stuff, along with a 7 1/2 HP Leeson Industrial motor (both compressor and motor rated at 100% duty cycle), the pilot valve, check valve, etc. including shipping for a little less than $800. I added a used (but in great shape) 120 gallon tank and I have a real horse of a setup.
The specifics on the compressors manufactured in Missouri are at:

specifics: Cast Iron head, cylinders, after cooler, intercooler and pump body. 5 individual concentric disc valves. Strict monitoring of Cylinder casting hardness complements the 4 Hastings USA rings. Connecting rods are precision bored Steel not Cast Iron or Aluminum and have Japanese world class full compliment needle bearings. Only Hastings USA machined steel piston rings. Tests show a 2-3 times longer life than Chinese made rings. Automotive-type, precision grounded crankshaft. Crankcase Breather Tube returns to intake so the compressor stays cleaner, better looking and quieter. Deep pitch Flywheel results in a 10 degree cooler output temperature. Non-asbestos Armstrong USA gaskets.
I can't tell you the prices going through Industrial Gold direclty because I bought mine through North Central Air (which I understand is where the Ind. Gold compressors were originally made).
If you are in the notion of building your own unit, I'd strongly recommend you contact REX at
