Hopefully Digital Camera Reviews will help:
They have have owner opinions and a side-by-side comparison as well.
A few considerations to take into place: power source (AA, proprietary rechargeable), storage media (xD picture cards, compact flash, smart media, etc...), construction (plastic, metal), optical zoom (at least 3x), etc...
After a couple of hours on the site, I am looking strongly considering the Olympus Stylus 300 Digital (3 megapixel, point and shoot), went to Amazon.com, priced it with an additional battery and 128MB xD picture card. The total is approximately $450 USD.
I currently own the Olympus C5050 Zoom, an overkill compared to what you are seeking.
edit: In choosing my camera I chose not to go with Smartmedia and I believe the current limit is presently 128MB maximum?
