Unfortunately, you won't buy much of a professional grade SLR camera for $600. Look at Adorama.com out of New York City. They are very reliable and you can look at all sorts of camera options. I strongly recommend considering digital with at least 3 times optical lens if your looking for a point and shoot digital. There are some very good point and shoot digital cameras out there that will probably do the trick and will be way below $600.
