Looking for a new camera, and have a selection in my budget:

D60 18-55 + 55-200VR - $1189
D40 6.1MP lenses as above $799
Olympus E-420 +14-42mm and 40-150mm Zuiko Lenses. $969
Olympus 510 lenses as above $929
Or a 420/410 lenses as above $789/$799

Opinions? Upgrading from a DSCP73, so the twin lens kits look attractive, and will be better than what I am using now.
