Throw a late one in here. How about the Pentax K7 as no one seems to have mentioned it yet. All recommendations have gone to the popular Nikon / Canon followers.
The Pentax has the best image sensor. With a fully sealed body on a metal chassis it should take plenty of (ab)use.
As the image stabliser is built into the camera body you have use of it without needing to acquire expensive and heavy lenses with it fitted. A further bonus is that all old K mount Pentax lenses will fit the new body. Plenty of cheap quality second hand lenses to choose from out there.
As for what to pay ignore the list price as there are plenty of very good deals out there. Most people just look at either Nikon or Canon as they have the advertising budget to keep there name in front and hence sales to people who just go with the popular choice.
