I continue to use my reliable Nikon Coolscan V ED, driven by VueScan. A 36-shot roll is six strips, scanned in batch mode with the settings I defined an eternity ago. I don't know precisely how long it takes, I rarely scan more than one roll in a session.
I can use the Super Coolscan 9000 for two strips per batch ... More setup time, but a bit more automated. Or I can use the BEOON and Leica SL for maximum speed in capture, and spend more time in image processing to do inversion and gamma correction. It all works out to be very similar in total time spent.
When time is an issue, I switch to a digital camera.
