Content Paradise has a DVD tutorial for Poser 6 that is really good.  I think it costs $40, but it is worth every penny.  I've been using Poser 6 for about 6 month, and I had bought the book Practical Poser when I got Poser.  While Practical Poser is an awesome book, nothing beats a video tutorial.

After watching the DVD, I learned some things that I did not know ever after using Practical Poser and working with the program for 6 months.  Two Thumbs Up!
