Thanks for the ideas guys. I definitely would have jumped on the ebay set, Smitty, but I'm strictly building a tourney set and have no need for the lower denoms. Plus, the guy I'm buying these from requires a minimum order of 500 chips, in lots of 100. I'd hate to have to order 500 of the 1000's. Nice try though.
I've yet to find out what the color of the 5000 chip is, but if it is gray like I believe it will be, it won't work with the gray 100's he has. So I'm feeling the only choice I have is to go with the 500/1000/5000 chips. I hadn't thought of starting the blinds at 500/500, but that's a very good idea Brewster.
I may try using the 2.50 (pink) chip as 25000, if I want to go the make-believe route. The 25 (green) chip would seem better, but that color is completely identifiable as a $25 chip, and pink chips are somewhat rare and unusual. I dunno. Do you think I can get away with using the pink chip?
