Granted, I got mine from a friend in Japan who picked it up on the street for me.
But still, you should avoid eBay at all costs for that item in particular. eBay sellers are known for gouging horrendously for that title. A while back (last year?) someone here sold a copy for around $100, which is much more reasonable.
I'm not saying you should necessarily hold out for a $50 copy, but £100/$200 is ridiculous. Recently there was a seller on ebay selling one for $350. I'm too lazy to check to see if it's still up. Highway robbery.
