I picked up a Senco 41 battery op nail gun for $10.00 with a case and 2 battery's from CL. The PO said it cycled and then would not work. I found that the clutch mechanism was jammed so I took the whole thing apart and suddenly it disengaged. I put 50 nails thru it and other than being slow it works fine. I found a place in the tool trailer for it and it will be a fine punch list gun, or for quick jobs. I have a pasload that I really don't like,it is unreliable and it seems to stop working just as you need it. So for $10. I think I did well. If it lasts 6 months it would be even better.
