i am currently in america guys and i have bought a couple of copies here.
i honestly don't know it games are region locked or not, however i believe it will play on a chipped PS2.
having looked at the box it is NTSC version, so if you are remotely interested let me know. i will be getting my ps2 chipped or whatever it is you young uns do these days, to play this game, and if noone wants the other it is no great panic.
maybe someone here has an idea of whether you can recode your PS2?
i will have a quick browse on the net to find out, however as i said before the wireless connection is intermittent at best.
failing that if anyone is desperate for a copy get in touch over the next couple of days and I will see if i can get a few more. shop i was in only had two copies so i bought them both!
