Does anyone have any experience using Omega compressors, specifically the PK-5020 or PK-5020VP?

I'm looking for a portable, electric motor-driven compressor that does at least 6 CFM @ 90 PSI for sandblasting. Possibly other uses later.

The Omega PK-5020 and PK-5020VP do 7.8 CFM @ 90 PSI, which should meet my needs. Just wondering if anyone has had any experiences, good or bad, that they can tell me about, or if they know of any other compressors that would be equivalent.

Thanks in advance for any and all replies!
