I would've thought that the two primary contacts were non-fussy as to voltage, but is this not the case? Do lower-voltage units experience more problems due to dirty electrical contacts, or do they run higher amperages through the camera that I need to be concerned about? I had been eyeing a Vivitar 283, 285 or Nikon SB26. I have an old pocket-sized Vivitar and will check it the voltage bit, out of curiousity's sake. I don't recall getting reliable voltage spike readings when using a cheap digital multimeter, but if need be, I've got a nice 100 mHz oscilloscope to use.
