Thanks for your input guys...

Most of my lenses are "old school" (FX) and I can not "properly" use them with DX camera
So changing won't be a problem - I don't have to replace any of my lenses (except DX fish-eye 10.5)
I think the old type pro-lenses aren't worse in comparision with today's versions.

I'm gonna switch for FX, because I miss the wide end and real perspective of FF (film) camera...without crop factor.

D800 will be over my budget, I was also thinking about used D3(s), but it is too big and heavy (I had D2h and sold it)

I was using D200 for last 4 years and was quite happy with its handling, performance and the results, but now want to go FX.
