I have a bag full of 283's that I use for slaved kickers, accent lights, anywhere I need a little extra POP.
I use them with quantum turbos sometimes.

The older ones can have REAL high trigger voltage so be careful if you haven't tested it with a Volt/Ohm meter and you mount it to any camera with electronics.

I always use a piece of electrical tape when mounted on a metal bracket or cold shoe just to be safe. I did get a "quiver" once when I had one on a speed graphic w/stroboframe.

You can get them for 20usd bucks a pop all day long on ePrey and if you ask sometimes the seller will know the trigger voltage since it's widely know among "strobists" that the older ones pack a wallop.

They are very robust and last a long time.
