<p>I agree with everything everyone has told you. That said, the bottom line is that if the D3x is in good condition I would go for it. The price is a steal. It runs like a watch and is built like a tank. It should stand up well to your regular use in hot, dusty conditions.</p>
<p>A couple of quirks to keep in mind: Outdoors, you may want to expose more for the shadows. The D3x sensor (at least mine) is very tolerant of overexposure before blowing-out the highlights, but underexposures tend to go black very easily. YMMV.</p>
<p>Also, while the D3x in high-speed mode can do a reasonable frame rate on JPG and 12-bit RAW files, at the maximum quality of 14-bit RAW (where I use mine) you might as well just set the camera for single exposures -- it takes over a second per frame (so bracketing may not be useful at that setting either).</p>
