For fans of the Rockman X manga by Yoshihiro Iwamoto, there is a great auction up for you on the Yahoo! block: all five collected volumes for 7,000 Yen ($70).
Often considered to be the Rockman X manga, Iwamato's 12 volume series was re-released and repackaged into five convenient volumes a couple years back with brand new cover/back art by the author himself.
Seller notes of a few bits of wear, scratches and bends, but nothing too serious.
Sure, it's all in Japanese but hey, if you love Iwamato's snazzy art style, don't let that stop you. If it does however, there's always Dark Neko's Lab.
