Here is a scan quasiprofessionnel (with obviously priced accordingly) which is more than satisfactory. It is rather light and ultimately no more space than that, but most importantly, it works with ease, swallowing an entire book as if He was a single flyer Installation is easy, scanning and verifiable by insight, correctable in size in format etc. And all very fast. All obviously depends on your volume of use that will allow you damortir or not the cost of purchasing; but otherwise this scanner is remarkable.
