How frustrating for SACD fans is this?

Deep Discount CD has a separate section for Dual Discs, but not mention of SACD anywhere on their site! (or DVD-A for that matter) If you want to find SACD's you have to search them out.

Why do they promote one and not the other? I went to Tower Records this weekend and they had a big stand up display of dual disc right in front of the door as you walked in. SACD's? All mixed in with the rest of the cd's. You have to know exactly what disc you want and whether or not it's even available on SACD if you hope to find one.

If dual discs sound as good as SACD's (my primary concern being the 5.1 mixes) then great. But why didn't SACD receive this kind of attention when it debuted?

(I guess I know the answer to that already though...SACD is a pain in the butt.)
