If your lucky and shooting a Nikon previously, then stay with Nikon just because of the lens interchangeability. I have the Canon FTBn, for sale btw, but it uses the old mercury batteries and one would normally have the meter recalibrated if wanting to use the in-camera meter. Lenses are great and the camera body is highly regarded as extreme temperature capable. The KX might be worth a look only because you can get some extremely good SMC lenses for it at very reasonable prices.
