Here's another "Have her, don't use her..."

If you're looking for something cartoony and different, try MDP's F-202.  She's free, has beautiful procedural shaders that look fantastic in Poser 5, and she's very low poly, leaving more room for you to add props, higher mesh clothes, whatever.

The downside is, she doesn't have much support.  Dynamic cloth still works, of course, and any modelled hair (vs. transmapped) looks great on her once it's refit.

If you're OK with spending money, Anime Doll is a nice option.  Not only can she use Maya Doll's clothes, it's possible to find an Anime Doll / Aiko hybrid, which kind of gives you the best of both (great looking cartoon character with great support and freebie clothes).
