Craftsman 75-piece tap and die set
Some guy at the flea market was selling this set for $50. Allegedly its been used but I looked at every one of the pieces and the only things that look like they were used were one of the dies and obviously the t-wrench. The cheapest used set I saw on fleabay was for $100, so this turned out to be a good deal. I asked the guy a few questions about it, including why it was so cheap, and he seemed to have good answers to the questions, so in the event it had a nefarious journey to the flea market I did my due-diligence in keeping things on the up-and-up
The only bummer was the set had the 'made in china' warning label that craftsman started using
