If you're looking to scan individual receipts, the Neat products are good. Most sheet feeders can't handle them. If you're looking to scan manuals and books, it's worth considering a book scanner like the OpticBook 3600. I really liked mine, but then the lamp died and it's absolutely impossible to get replacement lamps from PlusTek. Not sure about home sheetfeeders, though I've heard the lowest end HP device is not worth the money.
