There is a lot of good replies in this post. However the recommendation regarding a sb400 is not a good choice. First it doesn't produce much more light than the flash on the top of your camera. It does not rotate to the right or left. It does not stand high enough to not cause a shadow while using larger lenses. The only advantage to it is that it is cheap. Even cheaper when bought used.
I could not disagree more. The SB400 is small enough to fit in your pocket when not in use. Works great!
