Makehuman 1.0 is close to release, it is a human creator that can easily create models to be imported into a range of modelers/renderers. It features some nice new features that make it easy to create humans from a specific region of the world and the body shapes seem to be much more editable. Blender users will find a well established workflow documented on the site.
The makehuman generated models contain armatures that make for easy rigging and posing.
