- Always use SCFM ratings at 90PSI to compare compressors. HP rating are
- bullshit. I have a noname 2HP that runs 7.3 SCFM@90PSI, I just saw a 3.5HP
- at JC Penney that runs 6.0 SCFM@90PSI. What's wrong with this picture? Also
- my 2HP draws 18amps, their 3.5HP drew 14.7 amps. Under duty it was rated
- as "special". It's special alright... In compressors like everything else,
- you get what you pay for. Check out Harbor Freight, they had some decent
- deals on compressors when I last looked.
