If you're not hung up on getting the picture disc I recommend picking up the retail version. It contains more tracks and most likely better sound quality.
I know someone who also got lucky and found one of the picture disc versions recently. His copy had some noticeable PVC damage because of the sleeve it was released in. Does yours have any damage like this? Also, you might want to invest in an inner sleeve for it - or ditch the PVC outer one altogether (if you haven't already).
