I've posted on the other thread, but I'm posting on here too because I can.
Prices of the pins will vary, but are cheap enough so don't worry about getting the best price too much, unless you're going to the dealer! I do recommend Circuit Supplies, they were pretty good and just an e-mail away.
The very first time I wanted pins, I e-mailed AP directly who just sent me some out for free. You can't get cheaper than that
