I bought a Pentax W20 about a month ago and it is an exceptional camera. The auto focus is quick and the shutter delay is much less than my other digital, which was a real problem.
I had researched both the Pentax and the Olympus, and decided on the Pentax because it seemed to be the better value. Some of the feedback I recieved on the Olympus was very negative.
Going fishing tomorrow so I will try to post a few pics when I get back.
