Canon P-150M

The Canon P-150M is an ultra-compact and portable and fast USB powered A4 duplex scanner with 15ppm batch scanning capabilities and 20-sheet automatic feeder, all for less than 300 Euros. BTW: the Mac scanning software is included. If you connect the scanner it mounts like a USB drive so no extra software install necessary! Update: I tested the Canon P-150M for a few days and scanned more than 100 double sided pages in a very short time. Very fast and reliable! Highly recommended!
