If you're doing development of just about anything on Windows you need to get into the Empower ISV program. For $375 you get just about every major product MS makes. I just put it all together into a nice little binder they send. It's about 20 DVD's plus updates for up to 2 years.

Joining is a little painful only because the web form they make you use is awful, also you have to become a partner first (free) then you can register to join the Empower program. Anyway, now I can start full on testing of Win Server and SQL Server so this should be fun.
