I have a coolingmist stage 1 kit. I haven't used it much, maybe two tanks worth, thats about it.

2 quart tank, tapped
Boost pressure switch adj. up to 25psi
2 nozzles + tee
Fresh hose
relay
slow blow fuse
clog detector
inline check valve
New 150psi pump
Basically everything the kit came with and the on/off switch

I paid 380 + shipping for it (400). Like I said, I barely used it, no problems what so ever, I'm looking to get 300 shipped anywhere OBO. Ill also throw in some 18gauge wire that you'll need and some connectors for the clog detector.
