Well he gave it to me for free in exchange for the use of the joker model. He also has loads of free models and stuff for grabs and think the tutorial is the only thing he is charging for, and would say it was worth the money if you want to fully understand the process he uses. The tut is a download and think it also includes a couple of models and textures to work with.

To give you a rough idea though the process used involves setting up layers and rendering off the outline seperately to the toon shaded and comping them together in photoshop.
