I stumbled upon this one on Amazon. It appears this is the standard version of DWE-014 (which is the first-press limited edition version). It would seem that there were far fewer of this version printed than the first-press version.
There's only a partial image, but from what text I can see on the Obi, it appears that this one has 18 tracks (as opposed to the 19 tracks on the other version—my guess is that the instrumental version of the vocal song isn't included, but I can't confirm that without seeing a track list). This one also doesn't include the telecard that came with the first-press edition (Info at the very bottom of this page (NSFW):
