If you like some of King's work, his short story collections are enjoyable. More hits than misses, and if you don't like a story you can move on to the next one. Clive Barker's Books of Blood is also a good set of short stories. A very different (and much more polished, IMO) writing style than King's, but lots of intriguing ideas.
But short stories are not everyone's cup of tea, and King has often remarked that they're not nearly as popular as his novels. I tend to prefer short stories, so I have enjoyed his collections. Jerusalem's Lot, from the Night Shift collection, is one of my favorites. More Lovecraft than vampires, though.
