I've got an Olympus C-3000. it's a 3.3 megapixel. you can certainly get better. A year ago it was at a pretty good price point; I expect that currently somewhere around 5 megapixels is where the price/perfomance curve starts to drop off.
It has a slight (3/8 second) delay between the time I press the button and the time the image is captured... pretty annoying and makes for a poor camera choice if you're into action shots.
It doesn't take good pitcures in low light and it doesn't take good pictures when there's a lot of contrast between bright and dark (e.g. bright snow and shadows on peoples faces is a combination certain to produce a poor quality picture).
the eyepiece viewfinder is a little better than useless. If I want a picture to come out the way I expect I need to turn on the led screen (which really sucks the batteries) and use it to see what I'm getting.
There are models that have a slide cover that close over the lense and led screen to turn the camera on and off. I'd *highly* suggest a model like that for something that you'll want to take climbing (or do anything rough and tumble with.) In fact, just today, I was at the top of a pitch while helping with a climbing seminar and I asked someone to bring my camera up to me during their climb... now it has a crack in the led screen
however, even with all my negative press, it's still a pretty good camera.

good luck.
