I don't know which lens is the kit lens for this body, but I have the 18-55VR and frankly within its design capabilities (ie it's not an f/1.2 lens) it's a pretty d*mn good lens. It is WAY better optically than people seem to think, and since I own five prime macro lenses I think I know what sharp is.
If you're looking for something "built like the pyramids" the 18-55VR is not your lens, but if you just want something that's sharp and colorful, it really is pretty hard to do a lot better. Many people have upgraded to the 17-55/f2.8 and been surprised at how small the difference is.
