Don't know if it helps you any, but I remember reading a while ago that you can upgrade to any version of Vista from any previous version (Home Premium, Home Basic, Business), etc. by buying a key from Microsoft. You may not be able to get a BOXED retail copy, but I remember reading somewhere that you'll be able to upgrade for "a fee" to get the features of say Ultimate from Business for a price. After all, each version of Vista ships with the same DVD (different label), but it's all the same software, except your key unlocks a different version of the OS. I may be wrong, but I think that's how it was done... in that case you can still buy a PC, get the upgrade cert, and just pay the difference since it's probably cheaper than $400 Ultimate anyhow.
