Fujitsu ScanSnap S1500 Scanner – I’ve had one of Fujitsu’s S510 scanners for years, and it’s a workhorse. Excellent scan quality, good software, very reliable. The S1500 is a newer/faster model, and we’ve had the same luck putting these out in the field so far. If you need a desktop scanner for your office, it’s by far the best option out there.
