I don't know which camera to pick. I'm looking to do mainly portrait photography, hopefully professionally at some point, but in the meantime I am a beginner in DSLRs. I have played around with my father in law's D70s, but I'm still learning. I wanted to buy a D90 so that I could grow into it, but its a little bit over what I wanted to pay. So I, of course, am also considering the D60, D3000, and the D5000. Any opinions on which I should choose and why would be VERY helpful. I really need to decide soon as my point and shoot has died and I love taking pictures of my children. Thanks.
