Corel have their relatively new version of MotionStudio 3D on sale for $79.99 instead of $99.99, improving on the old ULEAD Cool 3D software. The trial period is only 15 days. This is animation software something like BluffTitler, except you can also create 3D models that can be used in BluffTitler. It's not overwhelming to learn, unlike the free Blender. You can export transparent SWF and uncompressed AVI that can be used as overlays in video editors such as Premiere Elements. A lot of fun to use.
