First unit I received had a broken servo drive right out of the box. After several weeks waiting for Pentax to deal with the warranty return, I received a replacement with a defective CIS (two thick black stripes across all scans). Judging from the many positive reviews, my experience must be a fluke... but two defective scanners, both with totally different problems? What are the chances? I definitely won't be touching another Pentax product anytime soon.
