If it exist CDJAPAN.com will have it.
I just checked, and last year a set of SACD-layer-only were released. I like having a red book layer on SACDs I get, because I often play them on CD-only players, in my car for instance, or make a copy for the car. Cost is $110 for six discs.
A couple of days ago I received from CDJapan, a set of SACDs of Bruno Walter's Bruckner performances. His version of the 9th is top of the line in my opinion. Slated for release next month in SACD are his Mahler performances. His Mahler 2nd is unsurpassed imo.
