Webucator recently made much of their ColdFusion training library openly available to developers at http://www.coldfusionmanualonline.com/
If you've never heard of Webucator, they are worth a look. They offer training, both online and in-person, for a wide variety of Web technologies. I took a DHTML session with them, and it was excellent.
PS – Thank you to Pete Freitag for passing this along to our user group!
