Haven't seen it mentioned here, but sonymusic.com is now sonybmgstore.com. They have a sacd button with many pages of sacds. The majority are classical, but they have some surprises listed there like The Rolling Stones, Genesis, Telarc Clasics (which I thought was an independant company), Mike Oldfield, Elton John, Steely Dan. Unfortunately, they only identifiy which are stereo, MC, sigle or dual layer sporatically.
