Impressive upgrade from D70

I've upgraded to the D300 from the D70 and I'm very impressed about the progress did digital SLRs from Nikon have made in the last few years. I Decided for the D300 against the D700 to be able to keep using my excellent 17-55 DX lens, to save some hard-earned cash and to keep weight and size down. Very satisfied with operating speed, 51-point AF system, large LCD and extensive customizability of menus and buttons.
