Hi, Carolyn, From my experience with Amapi 3-4 and Truespace 2-4, I'd strongly recommend Truespace for organic work. Truespace v. 3 has a great renderer and offers both sculpting, NURBS, metaballs and a very strong set of vertex manipulation tools - not to mention quite a few great plugins for organic work. Amapi has a reasonable renderer and reasonably good vertex manip.s, only simulated NURBS, and no metaballs. And you won't get Amapi for $99. And no, I'm not working for Caligari :-) Have fun
