I wanted to share my experience with a very reasonably priced, small, QUIET (60 dBA) compressor I just bought from Harbor freight. I have an industrial 2 stage, 80 Gal. Ingersoll Rand compressor but the noise in my home shop is so loud! It makes me jump when it kicks on. Also I just don't need all that capacity to do tool changes and run my coolant air blaster, shown earlier on the forum. This small, 2 Gallon 135 PSI compressor is perfect and I can install it in my machine shop, near my 1100 PCNC. Other interesting thing is that it loads up to 150 PSI indicated on mine. Has a separate output gauge, so you can turn that down to the 120 PSI the Tormach pneumatic tool changer uses.

If you are not into HF tools then take a pass but for $169 it cannot be beat.
