Large scanners (A3, 11x17, etc)

Rob

I'm looking for a scanner for sheet music, which is unfortunately just
a bit wider than the normal scanner (about 9").

I know there is the Mustek ScanExpress A3. Reputed to be OK but slow.
One of the reviews said that there is another low-priced scanner that
is reputed to be faster, in the $250 range. Unfortunately they did
not mention a name.

Any ideas? Comments about the Mustek scanner also welcome.

PS: I did try the scanner group, but no replies.
