I put together a little video which goes through rigging a head (not in great detail.. just to show how some of the tools work and the workflow). Also I had just woken up when i did it so i make no promises about the quality of content should give you an idea of how it compares to AM..
its about 7 minutes / 7mb - I'm uploading it right now and kevin is going to post the link to it once its done...

and heres the video which didnt show up in media player at the end
