Acer ScanPrisa 620U
From the Acer stable, the ScanPrisa 620U comes with quite a reasonable price tag. Also featured is a USB interface, and naturally, the scanning speed is much faster than the 620P. It comes bundled with a host of software like MiraScan, Copier, Xerox TextBridge. The bundled MiraScan driver lets you perform real time image-editing. But the scanner doesn't match up in the performance count, especially seen while detecting water droplets on the chrome jar. Scanning photos with bright colours is a problem area and the scanner also fails to make much headway with the darker areas. But with its near perfect detection of grey shades (midtones) it will definitely help not only novices but also more advanced users.
