What's the best SLR camera you know? (Detail>>)

So I like photography and I need help searching for a good professional camera.

I want the highest number of MPs possible. And I’d prefer it if people didn’t recommend the common canon/nikon 14MP one, I’ve already seen shitloads. I’m looking for something like higher that 20MP.
Preferably Nikon.
There’s a really good one I like it’s ‘Nikon DX3’ for 7500$
It’s amazing.
But if you have other cameras that are not Nikon I don’t mind checking them out.
Note: Good resolution, amazing quality/contrast. Literally pro.
Thank you. :)
