I get through a lot of crimp sockets (for 0.1" header pins), and it was getting expensive just buying a few hundred at a time. So, I decided to get a lot more, since that was cheaper, and I was anticipating price rises.
Good old CPC put them in a massive bag : ) I was kind of hoping it would have been on a roll : )
Anyway, at the price, I'm not complaining (they are 1 pence each in bulk, and they are of very good quality, and slightly gold plated). I get a perfect 100% repeatable crimp with AMP 90202-2 (frequently available on ebay for $20-$30 or so - I got mine for £15).
