jlv,
I'm guessing you've got the oilless variety like I bought the first time. Your limitation is what the machine can put out. I think you might get about 6 cfm at 90psi, which could leave you wanting more if you plan on heavy aplications. Impacts, ratchets, etc will be ok, but sandblasting, grinding, and sanding will leave you very disappointed. Also, heavy and steady use will preobably be the end of your compressor.
If you were closer, I'd offer to give you a deal on mine. Once I got the big one, the little guy just sits there looking sad.
