Another good place to get some stuff is PoserPros. They have a few V3 texture packages in their Proclubs line which is like $2.49 each. Other than that, yeah Renderosity has some under the freebie section. Also some of the subscription sites might be worth checking out. Poser World and PoserStyle both have textures and bunches of other goodies like clothes and props which you get as part of the subscription. No need to pay for each individual item separately. Pretty cool.
