I recently purchased a Mustek 1200 UB Plus (Australian model number - may differ for US) to replace an older parallel port scanner I had. It was extremely cheap just $100AU. To be honest I wasn't expecting much out of the scanner, but since I only really use it like a photocopier/scanner anyhow (I have a digital camera also) I wasn't too concerned.
The scanning quality is excellent for the price however - it totally amazed me there. The twain interface is very good compared to other scanners I've owned/used in the past, and the greatest part of all (and quite unexpected) it's very good at OCR due to the bundled ABBY Finereader program.
In the past I haven't bothered much with OCR, it's been too clunky and inaccurate to worry about. Not this time around. I placed a cheaply printed magazine page in the scanner and OCR'ed it through the scanners multifunction frontend. It scanned quickly, took almost no time at all to process the scan and output a perfect copy of the page to word, layout pictures, colors and all. Not a spelling error in sight. Everything editable. This finereader program makes Omnipage and TextBridge look stupid by comparison.
