Ok. It's yours pending shipping arrangements.
Considering the weight of the 520, and light it's not (I see some online listings that show it at 16 kg. which means roughly 36 lbs) let me see what's going to be involved to do it right.
BTW, did I mention that I have the manual and the DC cord as well? No mike, but I do have the 8-to-4-pin adapter with it.
