You might resort to making some of your own. Macmondo did a really cool Bryce Sci-Fi pic with dozens of "people" in it; none of which was Poser, or image based. His "Bob" and "Betty" figures were 400 polys each! I don't know if he still hangs around here or not, but you might IM him just in case and ask if he might consider sharing.
