A few years ago we had one of those traveling tool wholesalers come into town with their semi trailer loaded with tools. Waited till the last day of their sale and offered to buy all of their broken, non-functioning angle grinders. Got a large box with about 20 angle grinders in it - only paid $5.00 (that's right, FIVE DOLLARS) for the entire box load. Got them home and started switching & swapping parts until I ended up with seven good working angle grinders, plus a whole lot of spare parts. Can't beat that. LOL!
