Wing Commander CIC

Hi,

When Prophecy came out I had a crappy computer and couldn't play it. By the time I bought a new computer the game no longer selled (I live in Spain). I was thinking of buying this game through an ebay auction, but I've never done it before. Can any of you advice me? I'm a bit unsure of these auctions. Is there any other way to get the game?

Thanks in advance.

Zhak.
