I happen to be one of those lucky few who don't see it very often, at least not enough to be an issue for me. When I do see it it's usually under poor source content like cable television.
I own two Sharp Elites: the 60" has never shown a trace of pulsing, but the 70" has the problem several times during the length of any blu-ray movie. (Yes, some movies do seem to set it off more frequently, and others more rarely, but I've seen it with quality recent releases (such as Mad Men and Never Let Me Go) as well as with older fare (suc as Sex, Lies & Videotape). Since I have both televisions, I've had ample opportunity to compare them, and it does seem that not all Elites have the problem.
I also own a Samsung UN55B8500 - the last of their local dimmers in that size - and it has never shown an artifact like the pulsing.
