Some times I hate custom parts... After googling about, many sites want you to sign up to their service and then you have to request a price quote for the chip.

The only site I found that did gave  price is in China, and they only sell it in Lots of 10 for about $60, or $6 a chip. In my mind, cheap for a single custom made chip, but I don't need 10. Also its coming from China, so delivery to the USA is between 3 to 6 weeks minimum. I do not know about the rest of the globe. Maybe you can talk to them about selling you just a pair? Here is it's URL:
