I am a professional photographer.
When I am not working I use a Canon GX ( I think.). Not an SLR but about the most robust consumer camera out there.
Either one of the mid level Nikons or Canons will do the trick. But for that money you will come up a little wanting for lenses.
Personally, I would tell you it’s about the glass, and not so much megapixels.
That's what I've heard too. I have some "decent" Nikon lenses, nothing fancy (ie. not something that cost 2x the camera body). I'd say get a modestly feature-equipped camera with good resolution, and spend the money on the optics and a good flash for inside/evening pics.
