Go to eBay - search for "Epson Scanners." Scroll down that list and you'll find someone selling the Epson Large Format Scanner (12"x17"), model 836L, for $400 each. These are not auction items, but new, in-box warrantied products. And he seemingly has a bunch of them.
If I had the $$$ I'd buy one right now.
Good luck,
