They weren't cheap even around the release, i picked this up for about 80 GBP shipped to the UK, but it was Brand New with the Steelbook.
The cheapest i recall them being was around the 60 GBP mark on ebay for the steelbook version. That ebay one is a bit of a ripoff though since its used and the Japanese version so no steelbook.
Good deal if yours had the steelbook
