And if you want to treat this as a legitimate question about what's good in a digital SLR camera, I would say: lenses.
For instance, I still use a Nikon D-1X digital camera – it was the first digital model they made – because it is compatible with my large collection of – several thousand dollars worth of – Nikon lenses made for use with 35mm film. The image sensor in this camera is 28mm, almost the size of a 35mm slide, so the optics work with only a very slight reduction of image-space around the edges (and which is accounted-for by the viewfinder). Some of my friends who standardized their setups on, say, Canon equipment, did the same – although Canon has changed their lens-mount several times such that not all Canon-branded lenses fit on all Canon-branded cameras, and this was true in the film days as well. They bought digital to preserve their investment in glass.
It's really all about the lens, not the camera body with all its gadgetry. Any SLR is basically "a light-tight box with a shutter, that you attach removable lenses to." It is the lens, not the camera, that determines the images you can capture. I recommend that you buy lenses from the camera manufacturer, not a third party, even though the third-party lenses might cost less and/or seem to do more.
Every camera will have gee-gaws; more gee-gaws than you are ever likely to use, such that you should consider what features you will use. There are generally-speaking "consumer-grade" and "professional-grade" cameras. (My D1-X, for instance, was built for photojournalists.) You can expect both to be well-made. Consider battery life, and the ability to change battery packs in the field (as opposed to non-removable batteries ... never a good idea) ... that require the camera to be plugged-in to a wall socket. After all, when you run out of power, you run out of camera.
And finally, the ruggedness of the device! It's the stuff of legend that a photojournalist once knocked a mugger out with her camera. But you will drop the thing someday, and the camera should be able to take reasonable wear-and-tear and a certain amount of abuse without failing.
Finding a dealer in your area, and getting to know that dealer, is important when making a purchase such as this. I know of one dealer who also rents camera equipment, and he encourages potential buyers to "check it out over the weekend. Go shooting with it."
