After trying out several options for OCR, I love http://onlineocr.net.
It has a robust free version for documents for small and medium size PDFs. The paid version is very cheap, like 5c a page or something.
It is very fast and very accurate even for very blurry or crooked scans
This (up to a certain point) free web-based OCR software allows you to convert scanned PDF documents (including multipage files), faxes, photographs or digital camera captured images into editable and searchable electronic documents including Adobe PDF, Microsoft Word, Microsoft Excel, Rtf, Html and Txt.
Its most wonderful feature is, without any doubt, an uncanny ability to read texts in (jpg) comic book strips and render them speedily and with incredible precision in all formats mentioned above - and that in several languages. But rendering a pdf document in near accurate content and format in, say, a Word document is quite spectacular, too. Rarely have I seen a utility which delivers so much for so little. And if you want to buy more 'credits' than you are allowed for free per day, it's dead cheap to boot. You can even get bonuses by making a YouTube report, writing a review, or placing a mention in a well known blog or website.
Small drawback: the program says you can download multiple files by placing these in a zip folder. This has proven impossible - at least with a RAR compressed format.
Apart from this small boo-boo, do visit this site - you won't regret it.
