I just got a 7 hp 60 gal tank to replace my old 3.5 hp 20 gal unit. It broke a piston and quit and I needed one ASAP. I bought it at Lowes, Kobalt brand. I paid 499 plus tax for it, really a good compressor. It is a 2 stage compressor, I love it. It is reasonably quiet for a big compressor. The worst part about it was getting it home (20 miles, hair rasing ride, lol) The good thing about the compressor is that it is rated at 135 psi, at max duty cycle, 120 continuous use. You can run anything with it, air tools, sanders, blasters, whatever. Save your money and buy the best you can afford. You wont regret it.
