Wings3d, PovRay, I think TruSpace is still available.  Art of Illusion, Blender, Anim8tor.  Essential, PoseRay for file format converstion.  Posing commercial figures, Daz|Studio from DAZ.  Blender is powerful, but learning curve is very long, interface is confusing. 

Lo price, under thirty bucks, Daz sells a book, included a DVD with quite a lot on it, Daz|Studio, Cararra, Hexagon, I think Bryce, but maybe not. Good investment if you can get on with them.
