I think that it's the SACD/NTSC box set that's difficult to find, not the individual SACD/NTSC albums, which is what gene ordered. The PAL boxsets -- they've got so many of them, they're being used as doorstops, paperweights, etc. You may have quite a wait if you want the SACD/NTSC boxset, though, gene.
Being a Genesis Freak, I had to get the box set, cos I wanted those B-sides. And I'm glad I did, cos Nick Davis did a brilliant job on them; they really sound stellar, almost like new songs. (Although no amount of hi-res, remixing or surround sound can save Me and Virgil, but that's just my opinion!)
