One thing I've always loved about the .NET community is our willingness to share. I've recently come across yet another free avenue for getting a .NET overview - it's called .NET University. They are actually providing courseware that's starting to be taught in several major cities, and that you can also download & teach to others. The newest course made available is ASP.NET University, which will premier in Atlanta (Alpharetta, Georgia to be exact!)
Their schedule always shows a few courses available in Orlando, including an overview of BizTalk and Sharepoint. Hopefully this will catch fire and other courses & locations will be available soon.
