What you want to look for in a compressor is its CFM (Cubic Feet Per Minute) rating, not the pressure it can develop so much. Most compressors will put out 100+ PSI but they have to put out at least the minimum volume your tools or spray gun will demand of it. There’s nothing worse than running low on air halfway thru a paint job and having to watch your paint set while waiting several minutes for the too small compressor to build up air again.
If you want a large one, keep your eyes open for a body shop going out of business or upgrading. I found this 5HP DeVilbiss two-stage that way cheap and it only needed a guard made and a main switch. It puts out enough air to run several tools at once and has enough volume for beading or sand blasting.
Another option to get the volume is to hook two smaller ones together like these ones are. They aren’t in a shop but are used for charging a dry sprinkler system. When servicing them, I run them both together and they put out a pretty good breeze.
