Batch OCR with Scansnap

I have one of the “older” Fujitsu Scansnaps (fi-5110EOXM) that came with Acrobat 7.0 only. I moved overseas right after getting the scanner and was unable to get Readris by mail-in. Now, I have no OCR capability except for Acrobat 7 Pro which seems to be non-useful (won’t OCR, crashes). My scans don’t show up in Spotlight. :(

I would love to 1) OCR my past scans as well as 2) continue to scan in rapid succession during the day and have something do OCR at night.

My questions:

-Is there any software that will do batch OCR on my scans that is affordable?
-Is the Abbyy Finereader software with the 510M good enough that I should sell my current scanner on Ebay and upgrade? Does it batch OCR? -I saw an article that used folder actions to do OCR (http://www.macworld.com/article/60229/2007/10/nov07geekfactor.html?t=222). I could not get it to work with Acrobat 7.

Advice?

Thanks
