I made the big jump to VR a couple of months ago. For shooting in adequate light, it does not make a difference. For me, at least, it makes a huge difference shooting in the early morning when I typically am using my 500. I use a Wimberley on a sturdy Gitzo tripod, but find at shutter speeds below about 1/250 I am getting better results with the VR. I sold my old lens for $5400, so the difference was large, but not quite the same as starting from scratch.
