The 1st decade box is widely available, for instance here.
It's on sale till this weekend, you only pay € 11.19 which includes shipping.
It's shipped from Hongkong, so it takes roughly 1-3 weeks before you get it.
In the few cases I had problems with their deliveries they reshipped and I received it within 1 week after calling it in.
At http://www.cdwow.com/ you can see if they have a local version for your country, although 1 of the other sites is sometimes cheaper.

Makes me wonder if they have stuck DRM on a free game?
Does anyone know if this is the case or not?
Thanks

you unzip it and add registry info.
