Neil, just a thought, it is a great camera but you do need to know a little more than you would with the D80. The D80 has an auto and sports mode which you will have seen some people use a lot. In fact I rarely use any of the modes, I tend to shoot in either apperture priority or manual with a spot focus for bird photography. Therefore it doesn't bother me to switch between Andy's or mine...
It is always more difficult when you don't know the level where someone would like to enter...
and then of course we move into lenses....
