I'm buying a Canon Rebel XT where can I find it the cheapest?

I'm upgrading from my 6.1 megapixel point and click so I don't need anything mively expensive, but I am wondering where I can find it at a good price. I do have other expenses I have to pay coming up on my paycheck so the lower the better. So far Amazon has the lowest price, but it tends to fluctuate. I really would like to get the black one. Any ideas?
