Scott Bourne (http://www.twipphoto.com) posted a link to this site for Nikon shooters. I guess it's an online TV show with Scott Kelby and Matt Kloskowski. The past few episodes have been about the SB800 & SB900 (with references to the SB-600) http://www.dtowntv.com/
I did see those and even though I shoot with a Canon, there have been some useful tips along the way.
