No more oil-less compressers. Ever.
I lived with a succession of those miserable, noisy things for years, and started searching for a "proper" compressor when I was down to one 5hp-25 gallon DeVilbiss that was on it's last legs.
My criteria were:
Cast iron 2 cylinder pump
Preferably 2 stage
I looked at eBay, surplus sites, Craigslist in a 250 mile radius, asked people-essentially beat the bushes for 6 months. I looked at a few dogs, looked at a nice one that was local but on ebay and was bid out of sight.
Finally, on the local Craigslist I found a perfect condition Speedaire 5hp-60 gallon, cast iron, 2 stage compressor that had literally been used to inflate tires at a shop that worked on handicapped transit vans. The shop was closing and the seller was very motivated. I got it for $350, and also ended up with a nice Millermatic 185 mig for another $450.
Keep looking, the one you want is taking up valuable space in someone else's basement or garage. Buy American if you can. An Ingersoll-Rand T30 is nice, as are Quincys. Search for Forrest Addy's treatise on selecting a compressor, it's sage advice as one would expect.
