Uh, scratch my Contax reccommendation unless you can find a used one. The Contax I used (139 Quartz) originally belonged to my parents and I had no real idea how much it cost. A new, bottom end Contax body (no lens) is ~$650, lenses add another ~$200-$300 at least. Oops. Great camera if you find a used one in good condidtion somewhere. Nikon is a great company, and my "point & shoot" Olympus has been a great camera, I would assume that would transfer up the Olympus model line.
