i used an old large belt driven compressor that runs on 240 power..it was in a shop that i was fortunate enough to use...
problem here is they don't make many compressors which plug into regular receptacles that will run a spray gun consistent like you want them to...you need a large capacity, large horsepower motor on it...
I have a small compressor from harbor freight that i can use for touch up and minor sanding, but can't run constantly for long without it running out of needed air...
rental is an option but power will still be an issue unless you can find a really good one that runs on 120V...
