lightwave

*well, I can't really argue with the one other definition here; very stable, high quality graphics, proffesional quality graphics
-actually used in several dozen television productions, and current movies...
-personally I still can't find the texturing as convincing as a physical model, but if done right can get very realistic...
*though I wouldn't call $2000(US) cheap, it certianly is a fast download from Kazaa, or Limewire, or any other filesharer

Hey Lightwave7.0, a very realist CG modler, that doesn't take long to download

Lightwave

The best 3d animation packager avaliable, and is very stable and cheap.
