Was taking some indoor flash pics this evening and, on about the 4th shot with flash, a loud pop came from the flash bulb when it fired and its now blown. I could send it off for warranty repair, but I'd rather just purchase a spare flash bulb and replace it myself (doesn't look too hard to do with the aid of some precision screwdrivers). I'm aware that this would invalidate thewarranty, but it's almost up anyway.Does anyone know if these parts are available retail and how much a new flash bulb is likely to be? Has anyone else had this happen to them? For information, I've only used the flash a handful of times as I prefer to take non-flash shots whenever possible due to the far more natural light under non-flash conditions.
