One thing you have to consider is do you know how to use an SLR? If you do, then buying online from reputible dealers is ok. But if you dont then you may want to look at the more expensive local shops in your area. The reason being is that you will want to look for a camera store that offers classes free when you purchase the camera. Your ability to use the camera will be invaluable. Even if it is a couple hundred dollars more.

Those too good to be true sites... you should put their website into the Better Business bureaus search engine and see what your getting. http://search.bbb.org/
