Can anyone recommend authors like Ray Bradbury?

I want someone full of awesome. =)
I've read Martian Chronicles, Fahrenheit 451 and most of Dandelion Wine.
I also plan on checking out more of Bradbury himself, obviously.
Oh and I think I liked Martian Chronicles most. What I'm looking for is the horror-tinged moments of his stories.. not necessarily horror itself, I'm not into Poe/Lovecraft. And I'm usually not into sci-fi, either. So I'm not entirely sure what I'm getting at here. Perhaps someone else will see what I'm saying and can think of someone "similar" to Bradbury. Thanks.

I've found that Azimov was similar to Bradbury in some aspects. They were writing in the same period, but Bradbury is singular, and really without compare in his genre. I would recommend the book "Something Wicked This Way Comes" to you.

You say you do not usually read sci-fi, but you may enjoy C S Lewis' Out of the Silent Planet, Voyage to Venus and That Hideous Strength (I think that's the title of the last of the trilogy). They are a bit dated and have a sub-text but are enjoyable.

Philip K Dick wrote some stories that have been made into films - the plots have aged reasonably well but the language is a bit dated.

I enjoyed Robert Silverberg's Lord Valentine's Castle and the books that followed it - character wins over sci-fi fantasy. Lord Valentine is on my list of Fictional Characters I Would Most Like to Meet!

Try C. M. Kornbluth, if you can find any of his works. The ones he wrote with Fred Pohl are OK.
