I think Boogs encountered one of the few things you are likely to see go bad--the O-ring. (Which at least on a 110-A uses a specific sort of lube that they insist be used) Great thing is no probs if you flood the battery compartment, it's sealed off from the electronics so other than thrashing the batts, no problem. The strobe tube itself is typically good for 1,000s & 1,000s (and 1,000s etc) of flashes. Being 2-3 yrs old shouldn't be a problem unless it were maybe a rental flash that was used daily I suppose. Jeez, $300, ready to go w/ tray, arm & fo? Heck I'd buy it if you don't! // ww
