Aman to the compressor. Mine is a 5hp 20 gal Craftsman that is thirty years old this summer. It is only now starting to get weak. I paid sometime like 350 bucks for it new, and I can replace it for about the same. But the new ones will NOT last thirty years I would be surprised if one of these Chinese junk heaps will go five years. 5hp and 20 gal is on the low side of what is required for normal shop use. It will just keep up with a spray gun, and will run out of air for a sand blaster. A better option is an 8hp 60gal and entry level Chinese products are between 6 hundred and a grand, and they will be junk NIB. I'm going to see if overhaul parts are available for my old Craftsman.
