Mustek Scan Express A3 1200 Pro USB Large Format Scanner

I think this is the one I'm going to get. It's huge, not too pricey, and it seems to be popular with comic artists. I am a little skittish about how it'll work on my computer, since a few reviewers said they had problems with it on their Macs, but others said it worked fine as long as you install the TWAIN driver (which is included with it) and use a TWAIN-enabled program (which GIMP is, and I have). And I like to think myself computer-savvy enough to force it to work :P
