Most of the Free Stuff is based on the figures that are included with Poser 4. Of course, props work with all characters. If funds are limited, then you can model for a long time with the characters that come with Poser 4 (the nude woman is frequently called Posette, and the nude man Dork). In fact, there are lots of things in Free Stuff, at this site and at others, that have characters built from Posette and Dork with Morphs, Textures, Clothes and Props. There is a lot of good work in the community that is based only on Posette and Dork. If money is no object, then of course get Vickie and Mike. They will give you even more options. Ultimately, though, you not only have to pay for them, but some basic clothing for them. In general, clothes are not interchangeable between Vickie/Mike and Posette/Dork. Happy Posing! - JimX
