My 2 cents - spend the bucks on ViewScan, if all you got was Epson Scan or a hobbled oem version of Silverfast with your scanner.

Viewscan - in advanced mode takes a bit to learn, but it puts you, and not some automated wizard, in control of your scanners interpretation of the scanned output.

It also has an automated mode that works well for most images.

The up side of ViewScan is that it supports older scanners who had vendors that did not update their offering for the latest operating system requirements.

Just a twain driver and you are away to the races with your old scanner off of the local craigslist or camera club listings - 'next to free boat anchor for those running older o/s people'.
