CarGuy1 ....it cost me a subscription to TechNet...or not much different to the cost of Win7 Ultimate Retail [full] which I'd otherwise have been buying.
Slight advantage....I also have installed on the same machine...Office 2007 Ultimate....and the cheapest I've seen for that here was/is $999 AUD.
So far I'm a thousand dollars ahead, not counting a second dl of Win7 Ult...in the 32 bit flavour...
