Avoid Epson like the plague!
I cannot state this strongly enough. I have used several Epson and Hewlett Packard scanners, including flatbed scanners and film/slide scanners. I have never had a problem with HP; I have never had sustained success with Epson. Their drivers are all screwy, so if you have any other devices you will probably have a hell of a time getting the scanner to work.
I am confident you will be pleased with an HP scanner.
