Already answered? Oh well. I was going to say, for a one-stop-shopping program (models, animates, and renders) Carrara is one of the easiest to learn. The "rooms" system causes some to complain, but it keeps the windows uncluttered. There is still a Kai-ness about the interface that throws off some people, but other people (like me!) find it restful to look at and intuitive to use. And you can try a demo free.
