I have a chance to get a Curtiss Air compressor that he says is 20 years old 2 stage 220v and a Horiz. 60 or 80gal.Tank. I am not familiar with these and am looking for any advise.I will be able to hear it run when I go look at it.He wants $350 for it just not to shure. http://images.craigslist.org/3ka3p33le5O35Y25U5b8cd41097fbe2a21fe0.jpg
