I bought this Daniels AFM8 crimper on eBay last week. This is the same tool used by pro avionics shops to make wiring harnesses. Including the extra positioners, it would have cost more than four hundred bucks new, but I got it for just over a hundred. How can I afford not to save that much?!
Okay, it's possible that I may have a tool addiction.
It does a great job of crimping the little machined pins used in D-sub connectors, though.
