Besides getting the camera, do spare some money for the following (in order of priority):
Extra memory cards (depending on megapixel, if 3 MP above, recommend get at least 1 piece of 128MB card, ard. $80)
Battery Charger and extra batteries (for cams using AA batteries)
Tripod (depending on type of use, you could get the cheap ones for $40)
If you narrow down your camera to 2-3 (eliminate based on needs and budget), do check in at this forum and ask for recommendations before buying.
