I use an Epson V700 flatbed. It's tough to scan 16x20" prints, but I do that in four sections and then I stitch them together.
Since I don't own a digital camera this is what I do. It works, but scanning flat art sucks. It's so difficult to get it to look like the print, particularly toned ones are hard. You change something in the highlights and the mid-tones look all wonky all of a sudden. Often I will convert the scan to grayscale and then back to RGB and tone it digitally to look like the print.
