I am a member of MSDN Matt, I do not use the other methods which so many use. I'm legit I can promise you that. I removed the pictures myself to abide to the terms of use agreement with MSDN, having any picture to longhorn is not allowed because it is still under patients and every picture or screen shot must be approved by Microsoft. Odd yes but I'm not complaining.
The only way to get longhorn is to be a member of MSDN. There are many subscription plans as well as some academic alliances you should find the one that best suits your needs and wallet.
