Thanks all for the suggestions. I may end up purchasing the Millenium Girls at some point. They look great, but that's probably much more detail than I actually need to set up a sketch. Most of the paid illustration work I do is traditional hand work (3D-computer stuff is a lot of fun, but most of my clients want the old school type illustration using paint, brushes, etc.). I'll most likely just use the stock Poser children and add all the necessary details; clothing, hair and such, in the painting process.
