The first question I have (now that we know what your budget is) how serious are you about photography? If you love and have a strong passion for it, I'd say go with the 6D or 5DIII. (I'd go full frame for the type of shooting you do) also, You will still have money left over to buy 1 or 2 great lenses.
I ask this because with that type of budget, I would get a more current model camera that is a bit more up to date. Don't get me wrong. The 5D II is an outstanding FF camera. But it is a refurb, and the 6D and 5DIII are newer cameras that have more options.
It's easy for us to spend your money, and recommend more expensive cameras. But if you truly love photography, them I'd get something more up to date.
