I don't know about the rest of you, but I think I'll just find a nice scan of those $25 chips, print it out to life size, slide it into a flip and put THAT in my binder.
Prices that far out of range sort of take the thrill out of the hunt for chips as far as I'm concerned. How many illegals with interesting stories and real gaming history could I buy for that $499 or the $100 it would take to get the Cinco chip?
