Just a tiny bit late, as I just arrived home with a new camera . Yes the 7000 range is too expensive for me. Most reviews give the 5100 the edge on IQ, but I struggle to see much difference.
After much deliberating, I bought a Canon 600D. It was a bit cheaper than the 5100, and had a few things that I saw as being useful. Mostly though, it just fits much better in my hand. I felt much less likely to drop it. I bought it new, with Australian warranty, for not much more than grey market - so I am very happy about that. Now the fun starts. After a few test shots - all successful - I am now charging the battery, and reading the manual. (yes, shock, I do things like that)
A big thank you to the many people who have helped me, especially those who insisted I stretch the budget and get something better than I was initially looking for. Hope those who recommended Nikon aren't offended. The choice between Canon and Nikon was so close, I might have bought either.
