Actually, all of the PCs in our game are represented by Lego people, using approximations of the correct weapons and highly modified armor/clothing for each PC. (We had a female bard with a Scottish kilt made of paper, and one player currently caught up in a "manga style" phase made a long, black trenchcoat for his cleric. Our fire-based sorcerer has a flame-motif cloak cut from paper and colored with magic markers.) Monsters are usually just dice (with different numbers facing up to differentiate between "orc 1" and "orc 2"). I have a "directional" d8 - N, S, E, W, NE, NW, SE, SW - that stands in as the druid's dire wolf animal companion (we use the "W" to stand for "wolf").
Oddly enough, I have dozens of lead figurines, but I never use them when we game. They're unpainted (I don't have the skill or the desire to spend the time needed to acquire the skill to paint them, plus I like the way they look as-is) - I consider them to be "miniature statuary" on permanent display in the room where I do all of my freelance writing and D&D prep work.
