WT is right. New they are expensive but used can run $35-$70 depending on condition and things that come with it. I got one $40 shipped, used (but in great condition), with the universal mounting plate...but that was it. The hose I got with it was unusable for what I need, it didn't come with a feedneck adapter and it didn't come with an intelliframe line/plug. It did have all the jumpers for the board though and the glide wheels that move the paint were like brand new.
I have a wife and 3 daughters...yeah, the 4 Horsemen of the Apocalypse. You can't scare me....
