You can certainly get a good USED digital camera from eBay. I suggest for those who ask a Canon S40 or S45, S400, or A75 or A85 as excellent picture takers that can be had for cheap <$100. My S400 for example is still my point and shoot work horse that cost $400 new. It is worth far more to me as a camera than I can get for it on eBay ~$85. Compact flash cards and batteries are also inexpensive on eBay for these models. As you can probably tell I am a Canon user. There are also some Nikon models with the same characteristics as I described. With $100 RESIST the urge to get a new camera, all of the models in this price range will not produce quality photos. Remember also that a high # of megapixels does always reflect a quality camera. 🙂
