I have Carrara but I have decided not to spend any more money on upgrading this. I've been looking at 3D applications for ages now and have decided that if I'm going to buy another program it would be Maya as it's the best application for the kind of work I want to do. The only affordable application I will buy (if it's worth it) is Poser. I have to use this until I can afford Maya or Poser starts doing the kind of things I want it to do.
