True.
It all depends on why you're scanning them in the first place.
75dpi is fine when scanning with collaboration/quick-reference in mind,
but for archival/backup purposes (i.e. absolute peace of mind when your
whole collection of dead trees burns, drowns, or is simply disposed of)
or OCR, you'll want to go with 600dpi and beyond.
One common technique is to always scan 300dpi grayscale (or color) and
use clever software to upsample to 600dpi bw (of course somehow
segmenting scans into picture and text regions first.
What ADF scanners are out there for Linux that have high quality
reliable ADF, [...]
I wish I knew... If anyone on this list can think of a scanner whose
ADF doesn't require constant babysitting, I'm betting it won't have a
consumer-grade price tag.
I've heard nice things about the Fujitsu ScanSnap S1500
(http://www.fujitsu.com/global/services/computing/peripheral/scanners/product/s1500/)
and S1500M
(http://www.fujitsu.com/global/services/computing/peripheral/scanners/product/s1500m/).
About $450 or so from amazon. The S1300 is about half the price but
also slower.
Apparently the S1500's are supported on Linux via Sane
(http://www.sane-project.org/sane-backends.html#S-FUJITSU). Don't see
any mention of the S1300 (but it probably also works?).
