Bike porn

Sorry, ignorant newbie, who knows nothing of bicycle haute couture. Also I have a notion of building something around the same hub. I just like the "No nonsense, what else do you need?" stance of this model and it is one of only two bikes that I think looks good in orange, the other being the humble but worthy bTwin Vitamin.
Small pic just as reminder and in no way asserting that this is "Bike Porn":

Sorry to quote off subject here but that bike looks like a great bike for beater of some kind, but i cant find where to buy one, any one know?
