Hmmm..
I did a little research today...
You have some good information...
One possible find is the HP 5370Cxi, which seems to be a new release.
Right now I'm wondering whether the Epson 1200U would be better than the HP 5370Cxi..
They're both about the same price... $275 and both are USB.
On the side of specialized scanners, it seems the Minolta Dual Image II, or something is a decent choice.. $400
If you have any more information or want to help me out further, please continue to write in this thread... I'm subscribed to it.
