In response to the original question: Strata 3.0.2 is a really good program, so I'd say try using it. It's free, and fully featured. If your registration code doesn't work, I can email you mine. You can really do some amazing stuff in it, IF you have the patience to learn it well. It is somewhat unstable when setting up and rendering animations, but other than that I've had no problems with it. Check out some of my image gallery posts if you want some examples of strata work.
Keep us posted on how it works out!
