Perspective from a newbie: I've been working with Poser 6 for 4 months and avoid buying or using anything for Poser 4 - and usually Poser 5 as well. I have no expereince with earleir versions, so maybe I am naive about their benefits. As a newbie, my thinking is that the figures from perior verions are not as detailed, so I avoid them or discard/delete them. No one has shared a perspective of a new user like myself so I wanted to share these thoughts. Thanks for asking and evolving the community.
