Probably the best easy to use camera around this price would be the Fujifilm F70EXR, going for about $209 on Amazon. This one has an 'EXR' mode, which is a point & shoot mode specific to FujiFilm where the camera attempts to pick all the right settings, including for low light, portrait, macro (close-up) and backlit photos. This one has a 10x optical zoom, a 10 megapixel sensor, runs on SD cards and uses a rechargeable battery. Have a look at the user reviews on Amazon here.
If you're looking for any specific features, be sure to mention, e.g. whether you want it to run on AA batteries, prefer quality over zoom range, etc.
