Thanks all. I am looking at a Eaton, supposedly completely made in the US..

Eaton, unless they recently changed, are NOT completely made in USA. I believe pumps have been made in India for at least the past 10 years. A certain hot rodding forum even had a lawsuit or protest over Eaton claiming USA made, when the very heart of the compressors were not.
I know the pumps Eaton imports started showing up in many brands, and Eaton themselves has sold under different names. I bought my Eaton made compressor under the "EMax" name, a 27 CFM 2-stage, 7.5hp that is very powerful for my needs. It is carefully marked "Tank Made in USA", but the pump is India. The small finned intake runners (if that's the correct name) aligned quite poorly, one of them requiring me re-machining it to mate with the cylinder casting, so it would stop blowing the cloth/paper/tar/sludge mixture that
resembled a primitive gasket. And the entire pump assembly was coated in an almost hardened tar, covering very dirty looking rough casting. This I know because of the runner disassembly/cleaning/machining/repair.
The relief valves all appeared to be very primitive, visually much worse than a Harbor Freight special. Threads not even on the same plane as the body. After one of those blew apart and I actually looked closely, I replaced all of them ASAP. Those relief valves looked SCARY.
I do not mean to discredit the company, and my compressor works. It does, however, not get anything remotely close to continual use. I am pleased with the low RPM and the great CFM/SCFM. I was, however, disappointed with the fit and finish of the pump. Nothing remotely close to Rol-Air, IR, or even Home Depot brand compressor pumps. My EMax/Eaton pump looks very primitive up close.
They may be improved upon now, since I bought this one 8 years ago.
