I can't thank all who replied enough. Excellent advice all round. I'm sure I am in the "want" category without realizing that photo skills don't necessarily come with more expensive gear. When FX becomes the de facto standard I think that may be the time to make the switch. Until then the D7000 I think might just be as good as it gets!
Funnily enough I have golfed all my life & to a pretty good standard (single figure handicap) & the advice I say when somebody wants the latest go further set of clubs is, Skills first, the gear helps but is no substitute. Thnx again. BTW Stan I will be 3 days in St Petersburg next year before going on the Volga river cruise.
