A good DSLR camera? nikon or canon?

I have seen some of the answers here, and although I agree with the Canon & Nikon recommendations, let me add one more and give reasons for it. I liked and purchased the Pentax Kx camera recently. First when I went to look at the camera at a local camera store I found an uncluttered viewfinder. I also found that you could move the focus square all over the field of view. I love this feature and demand it in all my cameras. I like to photograph scenes that have a natural frame and sometimes that frame interferes with the focusing square, so if I can move the focusing square to the exact point I want in sharp focus, I am thrilled. Other features that I like was the fact that you can use any Pentax SLR lens on the camera from the past film days right up to the most recent digital model. The fourth and last feature that attracted me was that the stabilization was built-in to the camera body, which means you don't have to pay extra for stabilization in each lens you purchase.
