11x17 color scanner

Would anyone happen to know of a good 11x17 color scanner? It would be used for scanning in artwork and graphics. I have an Epson Expression 1600 right now and it works great, but it would be nice to have something that can scan a bit larger items. I checked out Epson's website but it appears that their 11x17 color scanners only work with Windows for some odd reason.

Any thoughts appreciated. Thanks.
