If you're a student, check out this latest offer from Microsoft: https://downloads.channel8.msdn.com/

Basically, once you verify that you are a student, you can download a free, full version of:
Visual Studio 2008 Pro
Visual Studio 2005 Pro
SQL Development Server 2005
Windows Server 2008 Standard
Microsoft Expression Studio
and more!

I'm working on getting verified right now

Thought some of you students out there may find this useful especially since they're full versions.
