DO A SEARCH!
Just kidding. (although, if you do search, you'll find a few more opinions)
IMO, a large number of night scenes are captured with the camera on a tripod--and you won't be using the SR on a tripod. If all you were ever going to shoot were night scenes
on a tripod, you might not need the SR. However, I'm finding the SR on my camera useful, and usually most people have an itch to shoot more than tripod-connected shots. I've handheld things that I shouldn't have (or couldn't have in the past), I've shot at 800 ISO instead of 1600, etc. The shake reduction, in this case, is my fudge factor (mmm..fudge).
I won't say that it's been an earth-shatteringly-awesome feature for me, but its worth a good price-check search. I think you find, at this point, that there isn't a $100 difference as MSRP indicates between the two models, at many retailers.
