Killzone CE Edition

[olliejjc16]

Hi guys, I just want to get a valuation for the original Killzone on PS2 Collectors edition. Apparently there were only 30,000 copies made and it is said to be the first steelbook game. I can't find it anywhere on the internet,on ebay or amazon. Only person I have found who claims to have had it was on this forum so hoping someone can help me with this. The version is PAL and its in pretty good condition.
