If you follow Chase Jarvis or Vincent Laforet then you've probably already heard about http://creativelive.com/
but for those who have not... it's a site that allows you to access any of their photo, video, graphics, etc.. training classes online for FREE.. but there's a catch! You have to watch it LIVE, but if you miss the session then you have the option to purchase it for download (if you pre-purchase then you save a few $$$$)
I checked out Vincent's HDSLR class a few months ago and while it was long Friday - Sunday, 8+ hours a day.. it was very informative and FREE! Typically a course like that would run $1k or more!
