I'll second Todd's impression of Astia 100F. I started using it recently and tested RSX-II in the past. Astia handles high contrast well and maintains an impressive amount of shadow detail. Having worked with Tango scans of both RSX-II and Astia 100F I can definitely see a difference in grain - scanned at 2000dpi grain is very much evident in the Agfa, and much less so in the Fuji.
