Well in my opinion it doesn't sound like such a great idea. Considering a legitimate version of Windows 7 starter is only $199, it is almost worth it to pay the extra $50 for the piece of mind knowing that you will have everything you need and will be able to get the proper support if any problems should arise! It would be a bummer if the illegal version you bought had something wrong with it and didn't work, because then all you did was piss away $150! Just my thoughts.
I hope this helps!

Yea its too good to sound true. In fact the only way to get that good of a deal on 7 Ultimate is if you were given a illegal version in the first place. Then MS will well you a legit key and send you a DVD. I got mine for $200 but only cuz a friend gave me a illegal version that I thought was the RC1.
I too would stay away from that. The best way to get a new OS is to buy it from a retailer like newegg or local PC shop. We get 7 64 Home Premium OEM for $150 and sell it to people. Has a nifty case and everything too.
