VERY excited. Just got word that the Nikon D90 (with 18-105 lens) that I recently purchased has shipped! This will be my first DSLR. All I need now is to scrounge up some money for a camera bag and a better memory card. Can anyone give some recommendations as to camera bags and a suitable memory card? I am extremely low budget (think broke college student), but would still like something that is of decent quality. I am looking for a bag that can handle the camera, some accessories and maybe another lens or two in the future. As for the memory card, what is the average that can hold at least 1000 pictures from this camera? Also, what kind of speed is necessary? Is class 4 good enough? Or should I opt for a class 6? I was thinking something around the 4gb range but was not sure if this was big enough to handle the large file sizes that this camera can produce. Any advice will be much appreciated. Thank you.
