iZotope RX2: Basic or Advanced???


I'm kinda going crazy here due to the price tease with Advanced.

I've used RX1 Basic since it's release to clean up vinyl records and cassettes for personal use. (Yet another aspect of my life converted to digital...)

Radius for Logic/STP has been on board for a while now.

Any user comment on why the other Advanced features are worth it would be appreciated.
