So I asked my co-worker who works in the digitization lab, and he said to him inexpensive means < $100 US and pointed me at -- you guessed it -- the Epson Perfection series (your link points at an Epson Perfection V370). They have higher-end Epson scanners in the digitial lab where he works, and he has this to say about them "We're still using scanners from 2007, so I think they make a pretty good product. And their software is made for people, not machines." Looking at the Perfection options here: http://www.epson.com/cgi-bin/Store/jsp/ProductCategory.do?UseCookie=yes&oid=-8172 I'd personally pick the V370 for artwork scanning myself. It looks like a nice compromise between features and price.

The only other thing to watch is getting it to work with your computer. Note in the Q/A section of the link you posted above people had to get the latest software from Epson to get it working well with a Mac. They didn't have problems, apparently, but it is something to keep in mind when you get the scanner if you buy this one. Here's its specific page: http://www.epson.com/cgi-bin/Store/jsp/Product.do?UseCookie=yes&sku=B11B207221

The technical features look nice to me -- in fact I'd kind of like to play with this scanner a little. Anyway, it also comes with a nice little selection of software applications for doing the little extras with scanned images. I really like that it comes with the stitching software -- so you can scan oversize items in pieces and then stitch them together. On that last page, if you click the "Technology" tab there is a PDF you can download under the "Scanner Resolution" section that has clear information at the end on what kind of resolution you might want. The enlargement capability for very small pieces is good with the wide resolution range. The LED lamp is nifty, too. It looks this printer would have things I'd be after for artwork I make on paper about US Letter size (approximately A4 -- it looks like it is designed to accommodate both at an 8.5 x 11.7 inch scan area). If you make pieces larger than A4/Letter, you might be annoyed the scan area isn't bigger (you could still technically get the item scanned by stitching it with the included software, it'd just be more complicated than just scan and go), but I don't think you are going to find a larger scanning bed in the inexpensive scanner price range. Those large-format scanners go up in price pretty fast, I think.

The only drawback I see for me would be (a) I do everything on Linux, so I couldn't use the application software and might have some trouble getting the scanner to work, but that's just me and (b) I'd like to be able to connect to it over wireless instead of having to plug it into the computer, for several reasons, including sharing the scanner amongst multiple computers. But I don't think either of those drawbacks would impact you at all.

I guess, what I'm saying is, that I have good experience with Epson scanning technology in my all-in-one, and other evidence from people I trust that Epson makes good scanners and is a brand you aren't likely to go wrong with. I like the technical features and capabilities of the V370 for the kind of artwork I do. If I were in the market for a flatbed scanner, I'd probably jump all over this one.

Hope that is helpful.
