Recently I bought a IDC tool ($10 plastic version) and it was stuffed after about 20 uses as the plastic fingers started wearing and bending so I wanted to design and get one made for myself. The beauty is it is double ended so in theory it should last you a life time as the pin pusher part is stainless steel and the handle is solid nylon.

You can find it via this link and will be around $35 total for both parts.

I will be ordering one over the weekend and then people can order in about a months. Currently the 2 insertion tips are slightly different to determine which is the best at testing with the final version to be updated in about a months time.
