I just recieved my refurbished D600 this evening. I am very pleased so far. It looks brand new, but the shutter count is 1426. It took me a while to find how to set the focusing to a single focus point, but I finally figured it out. I'm upgrading from a D300, that I've used for six years, so it's going to take time getting used to it. I'll get to take it out this weekend and get some shots with it.
