I've had very bad experience with overseas versions.
When I bought Utada Hikaru's "Dareka no Negai ga Kanau Koro - Single" I bought the overseas version and when I got the CD it had some sticky spray on the back of it. It looked like someone had sprayed it with bug spray.
When I bought Utada Hikaru's Single Collection Vol.1 there was nothing wrong with the CD itself but instead of coming with a translation of the song titles like most do, the back of the case actually had all the titles in Chinese. It was not removable either. Not an OBI, sticker, or translation.
Finally, when I bought Ayu's "Bold & Delicious / Pride" and "HEAVEN" singles (CD+DVD), even when I changed the region on my player the DVD skipped and moved extremely slow.
These purchases were all from YesAsia.
Now I'll only buy Japan versions. And I've never had a problem with them. And if you ever buy a Utada DVD, their all region so you don't have to modify your player. Just thought I'd throw thta in there.
