I have a Mac and, since the Army will not recognize that some of us work at home and don't have Windows, I got VM FusionWare installed. Now I just need a cheap copy of Windows XP to run on the virtual PC. I don't want Vista, there's too much work related stuff I need that conflicts with 64-bit systems. I don't really want to buy from a third party retailer that's untrusted. There's versions that are being sold online that have fake keys and/or burned CDs. I want a real, sealed, full version of Windows XP. Are there any retailers you guys trust out there? I'd really like to keep this in the $100 range, if possible. I know it's asking a lot, but I already spend an arm and a leg for Mac software. Thanks.
