I get this question a lot. There's a sticky in the photography forum worth reading.
Basically, what it comes down to is the fact that there is no such thing as a "bad" DSLR. Every camera on the market will take excellent pictures when used properly.
Pick a price range and go to the store. Handle every camera in that range. Click through the menus, play with the controls, really get the feel for them.
Buy the one that feels most intuitive.
