price difference of 600 vs 7000 is a few hundred $
Actually that is $1,000. That is a big difference to most.
Thanks for the replies. It seems like either way would work. I had considered moving to a m4/3. There doesn't seem to be an overwhelming reason to move to the 600 and very good reasons to go with the 7k (or its replacement).
Considering you have been using a D80 for this long, there is a whole slew of of cameras that have moved way past what it can do. I think the Nikon V1 pumps out better shots than the D80 does.
If I may ask, why a DSLR? You haven't really said why you want or believe you need one and what you are hoping to achieve with it. There is No right or wrong, but considering the two you are looking at, I can make a difference. It could be you could get just as good shots with something other than a DSLR. Or maybe a D600 is what you really need. All depends what you want to do with it.
