I have 1D MarkIIn but no longer use it, i used it few times last time 2 years ago, but then i used my 1D MarkIII more and didn't shoot with 1D2n as second body much, then last year i decided i will use only 1D3, but then i bought 1DX last year near the end of the year, so i will never touch my 1D2n again, even my 1D3 has no much use nowadays.
I am planning to sell my 1D2n and 1D3 and 1Ds3 locally so i can get another 1DX, hope i can find a buyer here locally sooner or later.
