Vista Biz64: Where's a Good Place to Get It For Reasonable $?

Where's a good place to get Vista Business 64bit? Vista Ultimate would be OK too as it's got the Biz functions.

I see Biz64 on newegg for $140 but that's an OEM version and says it must be resold.

The retail version is $278. That seems kind of excessive. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2060350368 1179212225&name=Business

I see Ultimate listed on eBay for much better prices. Is it safe to buy it there? http://cgi.ebay.com/Windows-Vista-U...14&_trkparms=72:1234|66:2|65:12|39:1|240:1318

I'd be leery of buying software on Ebay, but it looks legit. 100% positive feedback, and he's been there since 1999. I'm half tempted to go for it myself. My daughter wants Vista on her machine.

I would try and get Ultimate if possible. Also the OEM versions only come with either 32 or 64 bit while in the retail version you get both.

That is a really great deal. If its legit, I would get it if I didn't already have it.
