I've been using a Wacom Bamboo tablet literally for years. It's cheap, small and has no pen pressure sensitivity. Unlike the larger, more expensive tablets, it can be set so that it DOESN'T "map" the screen (top, left of tablet = top, left of screen). If you use it in mouse mode (I think?), you kind of hover over the tablet and can scroll the screen. Anyway, for basic photo editing it works great. If you need pressure sensitivity and fancy graphic designer stuff, probably not. My daughter has an Intuos Pro, medium, as she's an artist and she really likes it, but I only do photo editing and I tried the Intuos Pro for a while but preferred the cheaper one because of the ability to use their mouse mode. I think they still sell something similar for around the $100 range.
