I got roped into running something for Harn at an upcoming local game con. Rather than muck around with Harnmaster, I'm using blue book Cortex, which then makes me want to run a Serenity game, and hey what do you know, I'm back in the old days.
Anyway, I stumbled across this site, where you can get custom dice for almost anything. I'm ordering some d2s, just to finally have some. In the past, I've used d6s with pips colored in various ways, but it will be nice to have some with numbers on them.
Some of the dice that he has for sale are pretty neat.
