Thanks for all suggestions!
Scanning goes fine, and I've tested 2 programs yet:
Adobe Acrobat, and Scansoft Omnipage 15.
Both work good, but adobe works faster with my scanner(I don't always need to reselect the color and resolution).
A 100 page book takes about 30 minutes to scan.
then about 5 minutes until it's converted.
The only bad thing is, in Adobe there's no other way than to copy paste the text into word to check for spelling and scan errors.
Also, I noted Adobe's ok for English, but sucks at any other language.
But English books seem to progress better than Omnipage.
So far I'd advise everyone Adobe out of the 2 programs.
Also, Omnipage crashed a few times, and if you make an error, you need to start all over again,
On Adobe you can just continue scanning, and switch pages, or delete some much easier!
Only pitty my Dutch books don't get converted well at all!
