If you're looking for a slick program to build 3D models, I suggest Wings3D, found at www.wings3d.com. It's been steadily developed for over two years, has tons of features and is, IMO, fairly intuitive to use. Recently the ability to export the FBX format for models built in Wings3D has been introduced as a separate plugin. Motion Builder uses FBX as do several other 3D oriented converters and programs.
While my own models are not too sophisticated, I've read in the Wings forums where other Wings users have had very good success in exporting complex models in the FBX format to other programs including MB I believe.
While Wings3D and the FBX plugin are still "works in progress" I heartily recommend them for serious modeling.
