EDIT: I was lucky enough to find a new copy of Ar Tonelico with the artbook and outer box today at a Gamestop. I also picked up Atelier Iris 2 and 3 and Xenosaga 3 today, so I think I'm covered on PS2 RPG'ing for a while. 
I'm going to hold off on trading for now. Thanks to everyone who showed interest in my stuff.
