Thanks Jim.. In my case ALL of my scans done with the old ScanSnap FI-5110EOX had no text (e.g. no OCR done) as the software I was using for the past 7+ years didn't easily support it without buying a separate OCR package and writing some sort of scripts so they were all PDF image copies of the originals done using ScanTango.
I agree that IF you're scanning new material you will not need a pre/post OCR set of stages as it's all done at once. However, in my case where I was converting older documents over from the older scanner is when I noticed the fuzziness,etc..
As for the speed of the S1300, even at 100DPI the speed appeared to be the same -- something akin to about 15-20 seconds per page (duplexed of course) -- I just checked the specs and it's 4 pages per minute so that would be about right.
I've got a standing Craigslist search for an S1500M and if I find one for perhaps $200-$250 that works fine I may decide to upgrade to the much faster device.
If you buy one on Craigslist... be sure to check the version of Acrobat that is included. Also... it would be best if you knew that the installation was de-authorized on the old machine. When I bought my first S1500M... Acrobat 9 was shipping and the the ScanSnap shipped with A8. When I bought my second (for my daughter)... Acrobat X was shipping... and the Scansnap was shipping with A9. It seems that Fujitsu has a license to ship 1 generation old Acrobat. Given the price of Acrobat (about $450)... getting a one gen old version bundled in to the S1500M is still a great bargain.
I also did some PDF -> PDF+Text conversion... but not a lot. I honestly cannot say if significant image degradation occurred.
