One common technique is to always scan 300dpi grayscale (or color) and
use clever software to upsample to 600dpi b&w (of course somehow
segmenting scans into "picture" and "text" regions first.

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?).
