We were given a Mustek 600 CP by my father in law when he upgraded his system. Who would want outdated hardware?
I would simply say that this scaner is good for what it is, cheap and easy to use.
Its picture quality is good, and it is easy to use.
The software makes life simply, all you need to do is lift the scanner open and the memory resident software goes into action.
I can be used instead of a fax machine, or as a scanner, I have used it to scan and e-mail photos and there hasn't been a problem, also it has served as an emergency photo copier.
