"He who marches out of step hears another drum." ~ Ken Kesey
get a screw, buy a good one. piston are loud. air drops are handy throughout the shop, remember that when you're plumbing it up. We have them all over the place, helps clear lint out of fans and cools you off with a squirt up the shirt once in a while....
Get a Kaeser screw compressor if you can and never look back. Maintenance once a year and that's it. I'm serious.
