I am a fellow Brycer looking to get into modeling.
I am looking into getting a 3D app so I can make my own models. Basically I want to make objects that I just cannot find on the web for free. I use Bryce and Poser as my current 3D scene creators but I am looking to expand. I notice that Caligari has specials on Truespace (TS4 for 99.00 and TS5 for 299.00) I am just starting out so the 99.00 price tag is nice but... my questions:

1. Is TS4 worth it? probably, but should I go for TS5? is is that much better for the money (which is kinda on the tight side but I only have a few days left on the specials)
2. Should I save my pennies and go for Carrara ?(at 399.99 this would be my upper limit as I am just a beginner)
3. What is better TS or Carrara?
4. what would you do?

Any help would be very appreciated!!!!!!
