I bought a Nikon SB-600 for use with my D300 the day I picked up the camera.
Since I tend to do a lot of wide angle photography (building interiors and exteriors) the built-in flash is next to useless as the coverage is not well-matched to the lens (and you will always get a large dark spot centred in the bottom third of the picture as the lens creates a shadow).
The SB-600 does me fine and it's built-in wide-angle dispersion cover that slides out from above the flash head to hinge down in front of it is perfect. The flash itself is moved far enough away from the camera body when mounted on the hot shoe to avoid any shadow issues with the lens.
