I've been trying to find a scanner with a bed larger than 8.5 x 11; tabloid scanners get pretty expensive, and I've been unable to find a "legal size" flatbed anywhere, which would be the happy medium. Needs to be USB or firewire and the software's got to run on 10.3. It'll be used primarily for scanning images, so needs to be capible of a relatively large DPI resolution. Any suggestions?
