Kind of looking at cameras, is the Nikon D3000 a good camera? It is 10.2MP and comes with 18-55mm lens an a 55-200mm lens, 8GB memory card and the bag for $399 at Sam's club. I know some of the smaller cameras are a lot more mega pixels but I have heard of a lot of people buy this camera but don't know much about it. Any advice would be greatly appreciated.
