Recommend a camera for photographing items for websites

My wife needs a decent digital camera for taking photos of items for an e-commerce store and blog. It will be mostly clothing, and some small household items. The easier to use, the better, as she is not very saavy on photography. Something she can either hold, or put on a tripod and take pics of items indoors, using household lighting. The lights that are in the area she photographs in are incandescent bulbs, as I do know that florescent lights are horrible. She has a mannequin that has a white wall as a backdrop. Any recommendations? I'd like to spend under $500 ideally.

One feature in a camera that would be useful in her application would be the ability to do custom white balance. That lets you get the colors right under changing lighting conditions, as when some outside light is mixing with the incandescent, and does it in the camera rather than in later processing. Most better p&s will have it. But overall, ease of use is paramount. Image quality just needs to be good enough to sell used items, she doesn't need her photos to win awards. They just need to be good so people can see detail, and should not require any additional processing.
