You can use the SB600 by itself. To use it off camera however (and in a softbox) you will need a way for the D60 to fire the SB600. Your options wold be: SU-800 from Nikon. This is a dedicated COMMANDER unit that can be used on ANY Nikon dSLR body, so if you ever upgrade, you will always have that. It is only a commander and does not function as a flash unit. This is the simplest option, however an SU-800 costs 250 bucks. Pocket Wizards/Cactus Triggers. Cheaper option is to buy a SET of these. You will need two - one to act as a trigger/transmitter and one to act as a receiver. The trigger serves the function of the SU-800. Depending on what setup you get, Pocket Wizards can end up being more expensive as, at minimum, you would need to purchase two of these. The problem is, if your flash unit does not have a sync port - you are out of luck. Older Nikon Speedlites (SB-24, SB-26, etc) have sync ports so you could go the used market route and pick up some of these. However, you will ONLY be using these in manual mode so knowing how light is affected by shutter speed and aperture are a must. The final method is using infared transmitters and receivers. Essentially you are buying a "hot-shoe" for your flash (as opposed to a "cold-shoe" which is nothing more than a mount for your flash unit) and attaching a transmitter to your camera. These work on "line of sight", so if the receiver cant see your transmitter, no go. This is probably the cheapest way to go. If you are just starting out, and dont have money for Pocket Wizards or SU-800's, I would look into this. Cheap enough that you wont feel too bad about upgrading later, and will still give you the functionality of the flash.
