pricejapan.com has one of the coolest price (I think around 60,500 yen without shipping for a SL-C3000) around this region. However, unless you're a Japanese or somebody who knows japanese, you may need them to convert the OS to English.
A pal of mine who checked this out in tokyo last week told me that if they rip the OS into English, it would also rip the warranty!!! I don't how true is this but how ironic, no?
