I actually got it from a fellow racer from my LHS. From what I know, he brought it in a few times. The 1st time, he purchased 100pcs from a local distributor. (anything less than 100 would be quite expensive).
The 2nd time round, there wasn't enough orders to meet 100, so he got it from the famous auction site, if I remember correctly. I'll ask him, but I think that the prices that he got for the 2nd batch are similar to the prices that MysterE offers (US$2 per pc). Check out
