This is a newer (but almost identical) version of the one I have and that I used to paint my 93 Conv as well as countless other projects around here. I have had it for about 6 years now and not a bit of trouble with it. Being 60gal like others have said is the way to go as it doesn't run that often which IMO it is fine mounted in the garage.

It is 3.2hp avg and runs on 220v single phase.
