Thanks MJW, I've read that quite thoroughly before (along with every other D40/D60 review I can find) and still think that the D60 offers more of what I want at it's current pricing.
The cost of the D60 with the VR lens is less than buying the D40 kit and shelling out for a VR on top which mostly covers it for me, and the Active D-lighting seems to be very effective. Thus, from my point of view at least it's got more going for it in the low-light stakes (which will be my primary use) than Rockwell makes out. Plus sensor cleaning and a neater top dial. Obviously I'm open to suggestions too.
