Stay away from the oil free - they are noisier and don't last. You can get clean air using a separator. I would get a 60 gal with the uses you quote unless it needs to be "portable" to job sites.

Personally I have had a 60gal oil less craftsman 2 piston which blew up several times and was finally beyond repair.

Now I have a 30 gal no name from Costco - single piston oiled. Had it for many years of light use.
