I have one of these. Thought it was pretty good after doing about 50 -60 pages as a set-up test.
The project got sidelined till a few weeks ago. Tried to start again but the bulb would not light completely.
So far plustek has not seen fit to respond.
Google this unit and you will find that others have also had problems with ultra short bulb life.
If I ever get plustek to stand behind their product I will post here.
