I bought a D600 refurb from Cameta (another authorized Nikon Dealer) for the same price but with more freebies! The camera still exhibited the dust issue but a rocket blower to the sensor cleans it. No other issues and only had ~350 actuations when I first got it. Doesn't exhibit the dust issue after taking about 800~ shots with it. Very happy with my experience and I'm sure it would be the same for any name brand store that is a Nikon authorized dealer as well.
