I won't advise you on what to buy but stay away from photonation or bestprice. See the camera dealer feedback forum.
The good dealers won't have unbelievable prices but you'll get honesty and service and won't have to spend a few hundred dollars for a battery for a grey market camera.
There are also good dealers on ebay but be sure to check for authorized dealers with manufacturers warranty. Again, they won't be cheapest but will be honest. Don't do the package deals though as you can get better stuff for same or less than what's in their packages.
