Finished going through all the posts I could find which the subject seemed to have anything to do with compressors. To tell you the truth all I really got out of em is "don't get an oiless one" look at cfm but mostly it was arguments over 110 vs 220. :} I'm looking at this craftsman one. Craftsman Think it'll be enough for me? 6.4 scfm @ 90 psi, 8.6 scfm @ 40 psi. 33 gal tank. It doesn't specify wether it's oiless or not. And again, is 2 1/2 or 3 ton plenty big for floor jacks and stands?
