Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
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.
