Thought you'd like this one if you live in the UK at least. Check out this page on microsoft.com, where there is a huge pricing discount for TechNet Plus subscriptions. If you purchase TechNet Plus directly through that site (ie not through a partner) from now until the end of the year, there is close to a 50% reduction in costs. This means, for example, a years TechNet Plus Single User subscription comes in something like £270. If it wasn't for the fact I work at Microsoft, I'd consider buying this myself, and I'm honestly not just saying that because I work at Microsoft. I'm not, and never will be, a salesman, just a techie :-). With the full evaluation software included in the subscription, including beta's of the Windows Vista client and server operating systems and servers, it really seems to me to be excellent value for evaluation and testing.
