Query: Glass is filthy dirty

It's a good thing this scanner comes with a lot of software for fixing damaged photos, etc. You will need it to fix the artifacts introduced by the scanner itself. My unit came with lint specs and a filthy cloudy film on the INSIDE of the glass. And I'm not talking about just a little grime. I am very disappointed. I thought I was paying extra for Microtek quality.I have since noticed many other reviews for Microtek scanners with similar dirt problems.Microtek: you should be ashamed!The scanner itself is as slow as molasses, bulky, and the Microtek advertising on the lid doesn't help my room decor any.On the plus side, everything works seems to work OK and the scanner produces better results than my old HP and UMAX scanners. But I feel gyped (at least they came with clean glass). If I had bought this locally I would take it back. As it is I will either have to learn to live with it or try to take it apart to clean. Bummer.
