I am in the market for an air compressor. I have one that just does not put out the CFMS that I need. So I am looking to get a new one, well new to me. I am looking at a few of them and I was wanting your advice. I am needing one that I can run a Vaporblaster, motorcycle lift, sandblaster and air tools, not all at the same time. The vaporblaster uses about 10cfms at 90 PSI. I am just not sure if I want to go commercial and 220v or with a 110 hobbyist type. I would rather have more air than I need than not enough. I do not want to buy another air compressor down the road. I do have 220v plugs and a place to put a larger air compressor that is covered and out of the elements. 1st up is a "Kellogg model B335BL twin cylinder air compressor 5hp 220 single phase 80 gal tank runs great no leaks". The guy who has it says that he will sell it to me for $300, it seems that I can still get parts for it. It was used in a body shop so it has some pretty extensive use. 2nd up is the good old Kobalt 80 gal 5hp 240v. $450 used. 3rd is a Dewalt that runs off 110 and it says it will put out the cfms and it cost $1000 new with a 60 gal tank.
