I'll second the Craftsman compressors. I have the upright, 30 gallon direct drive (oil-less), 150 psi, 6HP and love it. Runs around $269 and if you catch it on a Crafsman Club day you get an extra 10% off and a free toolkit (hose, impact, ratchet).

Air compressors, like motors, there's no replacement for displacement. I'd go with a 30 gallon tank as others mentioned. 10 gallon tank compressors constantly cycle. The Craftsman one Doc suggests would be a great starting place.

If he is doing body work where an air sander might be running continuously he need at least 15 cfm @ 100 minimum. If he is useing an impact wrench non contiuous he can get away with a smaller one. I have a Craftsman 5 hp gas compressor that puts out 12cfm @ 90 psi and it's fine for impacts but not so good for continuous air grinding and sanding.

It all depends on what he wants to do with it. If it is a general air compressor, I would go with a 6hp,10cfm 20 gallon tank. If he wants to do some continuous work, ie sanding, blasting, air tools, etc I would go with more cfm and bigger tank. I bought a 6.5hp 60gallon tank, 23 cfm for $835 delivered. It ran a siphon blaster at 90psi for 4+ hours and did a wonderful job. Good luck, more cfm the better. Bruce
