Hey languard, I was using an Epson Perfection V33 which was doing a pretty good job on hand drawn pencil and ink maps and artwork. $88 or so on amazon.
I just got an Epson WF-7520 which is awesome. It does cost more but check this... scans up to 11x17 inches and prints up 13x19. Actually of you manually feed the paper it can do prints of 13x40 I think. It has been doing a very good job for me and the large format stuff is so great. I used to have to scan a large page 2 times and stitch them in photoshop. This is so much better.
