Actually, there's a lot of really great older Poser stuff that may or may not be available any longer. The one clothing item that has the most add-ons and textures is Anton's 5+ years old Morphing Fantasy Dress. From the Poser Cold Storage link EnglishBob provided, there's some nice scifi figures and a decent knight. The old Warhammer figures are still very cool and they've got to be around eight years old. Some Japanese made P4 Female figures still look very good and a lot of people are doing interesting things with the old P4 figures today.

If there's some interest, I'll cull out thumbnails of some of the better older freebies I've found as a nostalgic reminder that oldies aren't necessarily baddies. New textures can readily breath life in many an older figure or clothing item.
