Yesterday I placed my D5100 on top of a filing cabinet momentarily when someone came into the office to ask a question. The end result was my camera taking a 4 foot header on to a Marmoleum clad concrete floor, flash first..... I've already ordered a replacement D5100 and am considering whether to attempt repairs on my old one myself (I repair laptops and tablets as a sideline) or send it in to Nikon. Can anyone tell me about their experiences having DSLR's repaired by Nikon? Can anyone suggest ways to help me protect my camera in the future? (Other than NOT doing something incredibly stupid as I did in this case! :? - I still get a little nauseous when I think about it... )
