It really depends whether you want to do other stuff with the camera (make it a hobby).
My wife and I went with a Nikon D3100.
One reason is that we have a new baby, wanted something to last and take great pics. If you commit to Nikon or Canon then your lenses should last a long time (10 - 20 yrs), and you can sell your old body and update without spending too much.
We did lots of research, started with a basic 55-200 kit lens and a 35mm f1.8 prime (non-zoom) lens. It takes amazing portrait and low light pics like this (random example, my cat)

We found a good guy at clive anthonys, and he price matched internet stores like ryda.com.au. Best of both worlds, hundreds off asking price but a real store for warranty etc.
We can now expand to a 300mm zoom for kite pics, a macro for insects etc, a wide angle for landscape, etc. But we'll wait and see how much it gets used before spending more. (5000 pics in first 6 months..)
