On the off chance you return.
I agree with AKUK above firstly.
Its a generic enough question but I'll hazard a guess and say you likely have the old 18-55 and 55-200mm that are not vr. Vr is not the be all end all of lenses , but these newer nikon kits with vr have better optics than the older ones. What you have is a good set up, but both cameras and lenses have come a long way since the d60. I'd also hazard a guess and say if you are any way happy with this set up, that you do not need full frame,and a dx upgrade would be enough (ymmv)
For the price of an fx body you could upgrade your whole dx kit. Normally its advised lenses first, body then, but here your body is older and your current lenses will work, and indeed with a newer camera you should see an improvement in your ability to shoot in conditions with more difficult light.
There is a very small refurbished market where I am from, but I see refurbished stuff recommended here all the time, so maybe look at a refurb d7100. This camera will double you resolution, double your frame rate, add a stop or more to your hi iso shots, have better dynamic range, a far better autofocus system, a bigger viewfinder, better battery performance, twin card slots, better ergonomics with twin dials, shoot video, have a far better screen and has a degree of weather sealing if coupled with the right lens.
My second move would probably be to upgrade the standard 18-55, but in this case I'd go body first and see where I go from there
