Just purchased a used 580exll off ebay and am waiting for it as I type.
I tried to buy a new one, but after I ordered, a guy called to me to sell me some accessories and after I declined, my order got mysteriously cancelled!
Anyway, my question was what kind of things should I look for to go wrong with a used 580exll. I just started thinking "why would someone sell a 580 unless there was something wrong with it?"
Is there anything I should look for or test when I get it.
thanks
