Simple solution: I have a D600 and a D7000. I'm probably not going to buy a D7100, since the comparative tests I've run show only a very tiny difference between it and a D7100. Ken Rockwell wrote this comparison: http://kenrockwell.com/nikon/comparisons/2013-04-09-dslrs/index.htm The D7000 is so good that the additional pixels don't make much difference until the image is blown up to REALLY HUGE. Buy a D 7001 or a D7000 and a D600. The UI's are nearly identical, so switching between them is very easy, and you get the benefits of both, the reach of DX with the Wide Angle capabilities of FX. I'm rambling a bit here, but it comes down to what you like to shoot: Wide or Telephoto. If you have to choose, that's about it. I like having both.
