Ditto. I will sometimes add a vignette during the raw conversion, but all too frequently, I end up cropping it a bit more as I'm playing with it w/in PS and then I use an action which I found on the net. It add's it as a layer so that you can adjust the opacity. It's easy enough to make your own action for it though since basically all you're doing is making either a circle or elipse selection then adding a feathered gray gradient fill to the inverse and adjusting the opacity.
