You should also look at the Canon D2400U- also 2400dpi &48 bit. I am using one and getting excellent 4x5 and 6x6 scans. I recently compared a 4x5 color neg scan from the Canon with a Pro Photo CD hi- res scan I had done by a high end service bureau. The Canon scan had better sharpness, color fidelity and shadow and highlight detail. We live in interesting times!
