David,

I seem to remember the same thing. I believe that there were 2 different colored Hot Stamp chips and the Black Inlayed one. The hot Stamps were plentiful and were $5 or less each with the Inlays being slightly more expensive. They were all over Ebay for about a week last year. Its a real shame we cant search records on Ebay back that far, it would be a great resource if we could.
