I'm not sure what you have in mind, but always remember support. Even if Vicki wasn't the best figure available... it would still be a good choice because of support. A commercial figure from DAZ tends to have much more support than commercial figures from anyone else. Most other figures are specialty figures... they're good for certain type of renders, and don't have continuing support (meaning textures, clothes, etc.). Stick with something you know you know is going to be around in a year or two and that you will be able to keep finding things for.
