Does anyone really buy a camera with the KIT lens?
I've always as a rule bought the body, then picked out the lenses that I was going to use.
A comparison of " kit " lenses is fine -IF- you are going to buy a kit lens!
And given the OP is asking about entry-level DSLRs it seems a distinct possibility and a valid comparison to make.
Supposing you decided you wanted the Nikon D40. Here in the UK I know of no Nikon dealers that sell it body only, they come with a kit lens by default. I've seen some great pictures taken using the Nikon kit lens, so we shouldn't knock it, just because there are better, more versatile ones out there at greater expense.
