As you can see, this is James' attribution, not mine. The screen shot was take from the 3rd edition. I don't know what the 4th edition says about the chip.

$30 delivered sounds pretty cheap. I would take 3 red JSBs, or 2 blue JSBs, or 1 of any other color of JSB for the chip. I believe I have a couiple of others. I would have to search for them.
