That place in Chatswood, in Victoria Plaza chips em for $250. Steep.
My friend who had it chipped there has had no problems with it, comes with a three month warranty.
Didn't go so well for me...chipped and games work fine, but the laser is dodgy and they couldn't fix it after many times. The laser was dodgy before I took it there though, if that is anything worth noting. I don't think they stuffed it, because it was stuffed before. I just think they couldn't fix it. Now cos of my dodgy laser I have to boot it a few times before some games work.
And what's this rubbish about PS3? o_0
Rumours of another version of PS2 have been going around for a while (named PSX, what the hell?) but nothing about PS3...
