I have to tell you all- I have bought several Fujitsu scanners, sheetfed jobbies, the S510 and its successor, the S1500, and for straight-up document scanning to PDF, they are absolutely unmatched.
You drop a stack of papers in the hopper, press the "Scan" button on the scanner, and it slurps through the pages without pause, scans both sides simultaneously, does color-detection, auto-deskew and detects upside-down-ness, all on the fly. When the last page is through, a ready-to-go PDF pops up on your screen. Ba da boom, ba da bing.
Downside- no Twain or Isis interface, but when you buy it, it comes with robust software of its own, including a fully-licensed copy of Acrobat Standard and Abbyy Finereader OCR. For around $400.00 or so, an amazing piece of "does what it says it'll do" technology.
