Wow. If you do anything like mobile tax preparation, notary public, or need to be able to scan on the go, the Epson DS-320 is amazing. It really delivers on just about everything it promises. Ample power supply, fast and high quality scans (you'll slow things down if you go ultra high quality, but 300 is suitable for most professional applications), and the convenience simply cannot be beat. I've yet to have it jam up on me, and I use and abuse it regularly. It sits in my satchel with a bunch of other equipment so it does get knocked around a bit and it hasn't affected performance one bit. My only wish is that it came with a carrying case.
