My grandmother has a D40, and one of my buddies has a D50, of the two the D50 fits me better. Although I have limited use with either.
If money is no object I would not get a kit. I would get a body only and purchase good lens. the two lens in that kit to my knowledge are dirt cheap all plastic and not at all fast.
Get a d40, d50, d60, or d80 with an 18-200 lens and you should be able to cover almost any situation, add an external flash and your good to go.
If money is really no object get a body only with whatever Nikons equivalent to canons 24-70 f/2.8 L and 70-200 f/2.8 IS L and you will have some pro quality kit.
