I got one at an auction but haven't set it up yet as my shop is undergoing a facelift - or maybe I should say a 'hairlift'. I am replacing the old, drooping, blown-in fiberglass ceiling with poly panels. Had to box everything up and put it in storage so I could get the project done. Just need to get back to it.
Not sure that my post helped you much, but I do *plan* on using it once my shop is back together. I have a spot reserved for it...
