IIRC, there were a number of emails displaying continuing interest in SACD disks.
I received a blurb from the good folks at Acoustic Sounds and they're having what looks to be a heck of a sale on single and dual layer disks. Many for under $10 each.
If you order several, check to see if you qualify for free shipping too.
No affiliation with the seller, just seems like a great deal (although I haven't exactly been hunting for SACD's in a while).
