Well I picked up a nice Chicago Pneumatic CP772H 3/4" long shaft impact gun for free the other week! ~$400 new.
I was picking up another ~ 1000 gallons of used oil when I spotted it in the scrap iron bin at the auto shop that had the oil. They said I could have it because it was unrepairable. 
Well, One 25 cent O-ring to fix the blown out hose swivel, a $12 part order to fix the busted plastic indexing tab on the forward reverse spool button and 15 minutes of work and I have one more heavy duty impact gun to add to the collection! 
Now what sort of mechanic throws out a ~$400 tool because two very simple and easy parts are broken?
I don't know but thanks to those types guys like me tend to pick up some pretty good stuff because of it! REally, aobut half my collection high value commercial grade tools and equipment came from this sortof finds and believe me I have a lot of tools now! 
Anyway, anyone else got a story or several about some odd tool or high value item they picked up for next to nothing because some fool didn't feel like spending a few dollars and a few minutes of their time to fix a simple problem on a high value item?
Oh and my used oil collection just passed the 4000 gallons point which for the mini boiler that heats my small shed and old house that's about 4 winter's worth of free heat!
