A flatbed scanner is the only way to go. When you open wide your pocket book, you can grab HP's ScanJet 6300Cse Professional Series Color Scanner. For $399, you get, well, professional scans. The hardware resolution maxes out at an impressive 1,200 x 2,400 dpi with 36-bit color. Optical Character Recognition is built in to turn your scans into editable text.
If your work involves heavy use of high-quality graphics, then you'll need every bit of this scanner's capabilities. Otherwise, a cheaper alternative will handle the occasional scan just fine.

For scanning graphics for a brochure or a Web site, a machine like the AcerScan Prisa 620U will probably suffice. Like the HP, it has 36-bit color, but the resolution only goes to 600 x 1200 dpi. Not bad for most uses. The USB connection ensures reasonable speeds, though it won't be as zippy as the HP. One handy feature is the high-speed, one-pass scan that pops up a color preview in just five seconds. It comes bundled with ABBYY Fine Reader OCR and Ulead iPhoto Plus.
