Recommendation for a 11"x17" duplex scanner?

Archived from groups: alt.comp.periphs.scanner (More info?)

I am in the market to purchase a 11"x17" duplex scanner (preferrably
single-pass).

- I scan bound books as well as loose sheets. So, the scanner needs to have
a flat bed and ADF.
- Has to be atleast 256-gray and full color.
- speed should be min. of 20 ppm b/w and 4ppm color @ 300 DPI
- costs less than $3000

Please let me know what, in your experience, is the best scanner for me.

I am currently considering Ricoh IS-330DC for $2,250 at costco. Any reviews
on that?

Thank a bunch.
