I beg to differ. I have a 1 stage compressor that was purchased for $400. the CRM is 12.3 @ 40 or 10.1 at 90. even the DeVilbiss gun that was linked here requires only 23 PSI inlet pressure delivers 10 PSI air cap pressure and only 11.4 CFM required.
you can find some cheap compressors that will run thes, but you have to be very careful on which compressors you purchase.
