Query: New life to old flash

I thought I would never have a use for my trusty Vivitar 283 again, but boy was I wrong. These VP-1 units are hard to find, but for $22 I was able to turn my old autoflash 283 into a useful strobist tool. The only downside is that since its just a potentiometer, there are no positive clicks for each setting, so you don't really know if that power level is what you're getting. But its pretty close. It also allows adjustment down to 1/64th power, better than the current 285 HV.
