I should have mentioned the Millenium Figures Base is not the only required purchase.  You also need to purchase Daz3D's own Morphs pack of each Figure.  The figures are basically useles without them.  

The best place to get started with DAZ is at Download .com.  DO  search for DAZ, and you find free downloads to the Bases of Victoria 3.0, Michael 3.0, Aiko 3.0, and Hiro 3.0, in the Poser/DAZ Studio 3D Models Pack 1.  You'll also find Bryce 5, and it's Presets, there!
