What everybody else said, too many too list,besides SK,a few not listed John Sandford's Prey series and Virgil Flowers series,Stephen Hunter's Dirty White Boys,anything by Robert Ruark,Teddy Roosevelt,Joseph Wambaugh,Peter Capstick,Stephen Ambrose,Ray Bradbury,anthologies of short horror stories are always a good pick, you will find a great story here and there and lots of good ones..and One Flew Over the Cuckoo's Nest by Ken Kesey rereading at the moment..depends on your taste of course!
McCammon for growing boys, (and anyone else interested in some of the same down home as King does so well) Barker if you want to fight with your head and feel artistic, Straub in any way,shape or form and Ramsey Campbell if you want classic horrible beauty. You omitted Michael McDowell and shouldn't have.
Neil Gaiman. I think I would recommend "Neverwhere" as a starting point. If you like a little darker, then "American Gods". Or if you want satire "Good Omens", which is co-written by Terry Pratchett. I also can't say more good things about his YA book "The Graveyard Book."
All wonderful books!
I would also recommend Haruki Murakami. His books are strange and beautiful. Kafka on the shore would be a good one to start with, methinks.
