Devils advocate needed! Why should I NOT get a D3s?

+1 Get a D3s. Period ! I have D3s, D300s, D5100, D800 and a Sinar Back 54M that I use with various cameras. ( Hasselblad 500 CM. Mamiya 645 AFD II, Mamiya RZ67 and Arca Swiss M-Line Two ). I Print with my Epson 7900.
If I have to choose only one camera, no doubt will be the D3s.

Good luck

Luis
