Since we are discussing Nikons . . . Anyone have any experience with the D3100? My wife has finally admitted that, after killing two point and shoots this year we MAY need to get a DSLR. She likes the 3100 feature wise (and I can definitely make it work for model photography) but she always wants to know what real world experiences are, etc. I'd love to go with a D40 or D 60, but I need some ammo for the cost deflection issue . . . .
