Wayne,
just a thought, a great number of 220 volt shop equiopment can be rewired to allow use at 120V. You might pursue that as a thought. FWIW Make sure that whatever compressor you end up with has sufficient CFM to support your Gun. IO would stay away from samller "airbrush" compressors unless you only plan on using an airbrush, I dont beleive most of them will support even a detail sized HVLP
