I use Kodak powershots for my work cameras, and for hunting trips. I work in dusty environments (oil fields) and they hold up well. We generally have to use them everyday from spring through fall. The Powershot A2000 is a 10mega pixel camera if you want that good of resolution. Generally a camera in the 7mega pixel range is more than adequate. The only time more pixels come in handy is if you want to blow the picture up a lot. If you go with a pocket style camera make sure it has a tulip shaped mark on the image selector knob on the top. This setting is for taking close up shots of things such as flowers, or in your case engraving or proof marks.
