All the inexpensive scanners I've bought or used at work came with OCR software, most often Textbridge, plus an interface software, usually Paperport. I've found Textbridge to be quite accurate. A customer sent us a clean, clear PDF (that had not been made from a Word file but was an image), and Paperport pulled it up okay and Textbridge OCR'd it very nicely.
Just for your info
