Where to buy Unreal Tournament original?

[The Belgain]

I was wondering if anyone knew where it was possible to a largeish number of copies of Unreal Tournament (the original one). We're trying to set up some LAN gaming at work, and need to buy about 16 copies of the game. Needless to say these need to be legit copies.

Any ideas?

Yeah, or IT manager has approved it too, but on the condition that all copies of the games are properly licenced.

We're not actually managing to find a way of buying enough copies of the game though... very frustrating!
