What problem are you trying to solve?
IMO, people go a little crazy with edge connector repinning, and it usually isn't necessary to repin the entire connector. I think a lot of people are making money off of peoples' fears, selling them expensive pins they don't need.
For things like Atari vector games, it's generally just the 5V power and ground pins that carry high current that need to be replaced, as those are the ones that heat up and lose spring over time, due to repeated heating and cooling. The signal pins don't carry much current, and aren't subject to the same stress.
Even then, I've found that just removing the pin (with a proper tool), cleaning it, and just bending it out a little bit to restore some of the spring is enough to fix most problems (for another 30+ years anyway, especially for home use).
Also, what's equally (if not more) important is to keep the edge connector contacts on the PCB clean and free of corrosion, as most 80's boards (particularly Atari vectors) often have a layer of oxidation built up on them.
I use a fiberglass scratch brush, which you can get on ebay for about 6 bucks. I burnish the contacts, wipe them down with some Goof Off on a Q-tip to remove the metal/fiberglass residue, then hit them with a light coat of DeOxit on a Q-tip to lube and preserve them.
