Overall, there are about 113,000 Excel videos on YouTube.
Here’s a series of Excel courses from a teacher at a community college. The view and subscriber count on this guys stuff is pretty high. Looks like most of the videos are using Excel 2007… and some newer ones are Excel 2010. The guy has a recent (published Feb 2011) Excel book on Amazon (the review count is low but positive).
He’s also got a site with downloaded workbooks/excercises to go along with the video courses.
