To add insult to injury I also got 3 SnapOn torque wrenches at the same estate sale for $350. A 3/8" flex head, and two 1/2" covering 30-250 ft/lbs. They may have never been used.
Honestly it was one hell of a sale. The owner could have qualified as a tool hoarder.
Damn...Last estate sale I went to all I found was busted furniture and a box full of screw drivers.
