Estimates are s/h to be $10-$20.
There is no 100% confirmation on if you need to buy a computer system, piece of hardware, or simply the OS itself, to qualify. General concensus is you only need to buy the OS itself.
EDIT: If you plan to want to go to Vista Home Premium, it's cheaper to buy MCE 2005, since the upgrade is essentially free.
