If you're going to OCR, Nuance OmniPage is also very good, and I believe
costs about the same as FineReader.  We also use tOCR, from Transym,
which is Windows-only, but very accurate and cheap.  I have yet to see
decent results on complicated pages (technical papers) from either
OCRopus or Tesseract with the default models that they come with; I
believe they're both still aimed at book page OCR.
