Query: Works, but Just Purchase A New Scanner for Less

This document feeder works well; it comes automatically attached to the Microtek ScanMaker 5950. You can buy the Microtek Scanmaker 5950 for less than you can buy this attachment. So while this is a good unit, you can buy the unit and a scanner for less than the unit. Do that instead.
