Good thread. Glad to see Shirley Jackson mentioned so often.
My own list (I will try to keep this short):
Elmore Leonard - for dialogue and shifting POV
Shirley Jackson - for all rather reasons given above
David Foster Wallace - for those long, beautiful, looping sentences
Stephen King - natural storyteller, just hits all the right notes
John Irving - for World According to Garp, a perfect book, funny and sad and wise
Kurt Vonnegut - made me want to get a writer
