Full frame is the future. D700 is as good as D3 ($6k). Hence I sold my D200 while it is still worth something and all my DX lens and bought my D700 at Lords last week for $3920 including GST. Bought the 24-70 mm lens for $2250 at Lords too. Has to top up more than $3K, No regrets. Pictures are great even up to iso 6400. With D200 I could get good pictures up to iso 800 only. D700 iso is incredible and unbeatable. Canon 5D is no match.Go for it.
