$2,200 from Airgas, free freight, could be sitting in my garage next week...thinking...
I can't seem to find it through Airgas, but I've found the kit other places for $2500.
I have the woodworking equivalent (Festool MFT), and it's the most used tool in my shop (and probably more expensive by the time clamps etc. are included). If this would get as much use, I'd definitely pull the trigger.
