<p>Will be upgrading my DX to an FX camera in the coming month. I do a range of photography from sports and special event. A photographer is selling his Nikon D3 for 2,500. Is it worth me buying this (body only) or another for a bit extra? (D800/D600). Wouldn't want to upgrade for a while after this purchase as I would be focusing on buying suitable lenses. <br /><br />Any advice would be appreciated.</p>
