James is right on. One big benefit of digital is that frames are free — we tend to shoot humongous number of frames as compared to what we used to do on film. On a typical shoot — say, for me, a theatrical performance — I'll capture 500-600 frames in two hours. And when shooting action, sports or birds, I'll clip away at 4 – 10 FPS, depending on the camera body!
Enjoy your soon-to-be camera. If you can find a D300s, all the better!
