I just purchased my first DSLR, a Nikon D40. I am about to buy a basic lens (18-55mm f3.5-5.6G/AFS DX). Should I get the VR on this lens or doesn't it make that much difference? I plan to buy the Nikon 18-200mm VR at a later date for travel. Thanks Sorry, there's supposed to be a question mark in the title "VR Lens Needed?"
