Pluralsight offers (or did when I joined) a free 30 days for video trial courses....they just bought another company (forget the name) and there are now more for the "Pro" membership. I have found both worth the money (I pay it myself) as I do some IT stuff for fun on the side. They have a 8 hour course on "SQL Server: Logging, Recovery, and the Transaction Log" for example....good stuff....
