Same here. I started in 2005 with a D70. Since then I've had the following: D70s, D200, D40, D60, D90, D7000, D7100, D7200, D600, D610, D750, D5500 (X3) and now Z6. The D600 was the only one I ever sent in for repair, and that was because of the spots-on-the-sensor thing. And they gave me a new D610 to replace it.I'd never had an issue (ignoring that whole D600 thing) with a Nikon body. Ever.
