I found this tech sheet on boardgame geek. It's the one my group has been
using for quite some time. We play with racial techs and this tech sheet. Everyone
get's one and marks their techs with pennies. I like it more than the default
tech sheet as it gives more options for researching tech and most players can
read it...after being walked through it once or twice. Personally I couldn't
imagine playing with the cards the game comes with, my sympathies if you have
played this way.
