Depending on how you feel about board or tabletop clutter, it's pretty easy to go to a dollar store or Wal Mart and pick up a cheap set of plastic poker chips and a Shar-pei marker. If you're feeling moderately creative and are over 18, add three cans of different shades of green aerosol paint and one blue can and you're in business. That's how I made blip tokens for extra sets of tournament Space Hulk. If pennies weren't so hard to pick up, at least for sausage fingered Fantasians like myself, they'd be the cheapest way to go, and if non-slotted plastic bases were easier to find, they'd work too. As for cards, the actual topic of this thread I guess, I like them a lot for initiative, but they do clutter the board and detract from the overall aesthetic.
