help in compresser size

Small compressors can't keep up so they run and run and run which is not only noisy (unless it's an old speedair or something like that) but they also generate a ton of condensation which comes out of your tools. Tools that spin, like a die ginder for instance suck a ton of cfm. The bigger the better if you can afford it, also bigger means 220 wiring so you have to take that into consideration.

The one I have is 30cfm at 100psi and even that runs more than I like although for painting it's fabulous, barely comes on.
