I have JoePublic's D3 and V3 weightmapped figures. They are really good. With a Poserworld membership, I have clothes to last a lifetime. Also a number of morphs and textures available.

Like AetherDream says, we have really good characters, but no vendors support them. Rex and Roxie, made by the creator of Miki 4 are also good, but have little support. That is a real shame.

Anastasia has more support than most. I have probably more than a dozen outfits, with a good variety. But that market dried up pretty fast.

I got tired of V4. Apparently, so are a number of vendors and customers. I don't use V4, and buy or scrounge whatever I can for other. Working on Blender, but slow going.
