My favourite figure is Antonia Polygon by odf. Antonia bends better than any other figure I have used, is free, and there is a very nice free texture set for her by Saint Fox. On the down side there is not much content available for her as yet in terms of hair clothing and accessories. Antonia is still in development, but nearing completion, so I am expecting much more supporting content when she is finished. In the mean time there is some stuff at Antonia's Free Site.
