I bought one of those used a few years ago for $900 with a brand new Baldor motor on it.
It works fine, but I wouldn't say it could hold a candle to my Champion Compressor. It sure looks better, though with that red paint.
Seems like the Snap on is an off brand compressor - IMC or something like that.
No way I would pay anything close to 5 grand for one, when you can get the premium model Champion for about $2500.
