When I was shopping for my 10D I checked with a number of the "cut rate" dealers like this. I found it very interesting. They are very high pressure. If you try to order on line you have to call them to complete the order. When you call they start in on all of the extras they want to sell you like flash cards, other lenses and so on. If you tell them that you don't want any of the extras they will tell you that the camera is out of stock and not sell it to you.
I had one actually tell me that the 10D came with no battery, cables or software and if I didn't buy the above from them they would not sell me the camera.
Stick to stores that you see users here talking about and you will be able to leave your Excedrin bottle in your desk where it belongs.
Dealing with the other places is kind of like the light is on but nobody is home.
