"Bill,
Two stage is necessary to get to 150-175 psi. Unless you have an in-ground lift or a tire changer, there is little need for that high of pressure. Most air tools call for regulation to 90-100 psi which a single stage will do."
Paul and Bill,
The issue of a single stage or a 2 stage compressor is just as you mentioned. Most tools need a supply pressure of about 100 PSI. Your holding tank is full at 120 PSI verse the same volume tank starting at 175 PSI..... I guess in the end it depends on what you will be using it for, but a single stage will run much harder if not constantly to run many tools. I refuse to keep taking a brake to wait for the tank to fill up again and again.
