Query: Good buy

Great little flash unit for Digital SLRs that are compatible. Unit is small and lightweight and low profile on the camera allowing for better maneuverability. Has a boune function as well which is great, best for horizontal shots rather than vertical shots because it does not swivel. Uses 2 AA batteries. Would recommend as a value purchase over the SB-900 which has more bells and whistles, but is 5x the cost.
