Summary: Please note: I purchased a somewhat different model - 6100 Pro - over 1 year ago. I was unhappy with the purchase from the onset and have subsequently purchased a Canon 8400F ... a great scanner. The Microtek took very good scans from photos and film (35 mm slides). However, it rarely worked.
Summary: The quality and clarity of scans is excellent for a mid-range flatbed scanner. The options to scan reflective, photo negatives, and transparencies of all sizes made this an attractive purchase. The cover can also be raised for book scans.
Summary: I purchased the Microtek i900 flatbed scanner a couple months ago. I use a scanner for a lot of things for which any cheap scanner would suffice, but was looking for a scanner with a higher density rating for scanning my artwork, which frequently has lots of subtle darks.
Summary: When I first got this scanner, it took me about ten tries to install the software so that it worked. This is a known problem, and all they tell you is to try reinstalling the software. Their flowchart for troubleshooting pretty much says "if anything goes wrong, reinstall software.
