I see this disc regularly used for $75-100 bucks and this one unopened for $345 is outrageous. The DVD of the same concert can be obtained for around $10. I haven't heard the SACD, but can it be that much better, or even as good as the 5.1 mix on the DVD. The DVD is a very ambience only in the surrounds mix, so is the SACD really worth it aside from the rarity?
