when i started body work, i blew 3 craftsman compressors..lol... not my favorite by any means... go with the 2stage compressors much better,, I bought a cheapo from tractor supply place it was a 7.5hp that did a decent job it had a 60 gallon tank it was like $400.,, and on a big spray job,, it'd start to get low by the end, but it still did ok.
but right now. i've got two really good compressors... one is a 7.5hp on a 120 gallon tank and a 10hp on a huge ass 240 gallon tank that i got from my uncle... way over kill but i can have two people sand blasting and two people sanding and never have a prob with air...lol.. but right now it's just me so i only run the small one... but sometimes i forget to turn it on in the morning, and with all the air I usually dont' notice till the end of the day.. even if i'm painting,, it's insane...lol....

also check harbor freight for compressors last time i was there they had a few decent ones for around $400.
