I've settled on a two-stage compressor rated at 175psi and able to deliver at least 14cfm at 90psi. But now that I'm in the shopping mode, what's the difference between a $1200 Quincy or Puma, a $1000 Ingersoll-Rand, and an $800 extreme duty Campbell-Hausfeld? The specs are really close between the models. What makes a Puma worth $400 more than a C-H? (BTW: Those prices include magnetic starters where required.)
