My air compressor is giving up the ghost. The tank is rusting through little pinholes. Epoxy works to plug it but it is just getting too bad. It was my dad's so it has had a full life. Does anybody have a recommendation for a good air compressor? I'd love to spend under $400. I have several air tools and three nailers. I also have a small sand blast setup that I'd like to be able to use. I'm guessing I need around 5CFM at 90 PSI but that's just a guess. I also want one that requires oil. I know it's a long shot on here but does anyone have a suggestion besides putting the air hose up my anus and/or pee pee hole?
