Looks like a good unit and the information had the correct low down on horsepower ratings for compressors. I currently have a two stage Delta, about the same price. Hooked it up with an extra 60 gallon tank from an old worn out single stage I got at an auction for $20.00. The 80 gallon tank on the Delta plus the extra 60 gallon tank really helps the air capacity. I put water traps after each tank, then my filters. Works great.
