At the risk of being permanently banned by Bouville... MDB is godawful. Steer clear.
If you like Blackwater Park, you'll certainly like Deliverance or Ghost Reveries. And actually, the Lamentations DVD is a hell of a buy -- I got mine for $12 at Circuit City. Not bad for 2 hours of music (+ band-in-studio featurette).
So well informed I don't know where the truth begins.
