If you don't mind spending a bit more, the Litko plastic stuff can be customized. I've seen some really nice looking chits and markers for everything from PG, AA:Minis, to OCS.
Or go the cheap way and raid your Bingo, Tiddlywinks, and tile spacers.
It's all good.
I'd never heard of those before.
Here's a direct link for anyone else out there like me.
