You're probably right about the cost/performance idea. Still, before I get back to the Last few pages of my thesis, maybe I'll try feeding parts of my most vanilla image-PDF file to an opensource OCR program. I'm pretty sure there are a couple in ports. IIRC, though, the images have to be jpegs of tiffs or the like.
