Do you need to replicate a darkroom-style contact sheet?
I currently use a Canon 8800F, which takes 2 strips of negatives at a time, and take 1 1200dpi scan of the area that encompasses the 2 strips. From here, I take the file into lightroom, crop out the individual frames, and use photo-editing software to auto-level and sharpen each frame.
This leaves me with a 1650x 1100 pixel scan of each frame, perfect for web use, and image evaluation.
I've just started to do this, but I needed to do something, as I only get to my darkroom every 3 or 4 weeks, and to be honest am not overly fond of spending my limited darkroom time making 35mm contact sheets.
I feel differently about 120 6x6 contact sheets which I consider a thing of beauty, and more like 12 small prints, than just a contact sheet. Thus I will continue to make wet-printed 120 contact sheets.
