I can almost say "all of the above". We use plastic ones. pewter ones and I certainly wish I had more time to paint them. those I do manage to paint usually turn out very nice. In games we'll use dice, counters, pebbles, Doritos or whatever is handy on the battlemat. We used to use our imaginations but man, I really like it better with minis. Much easier to get done with combat and get on to roleplaying. And when the new prepainted plastics from WotC come out, I'll be all over them.
