To answer KCWs question I have to say definetly. When it comes to Sci-Fi and Fantasy I've read almost everything.I've read everything by King.
An excellant though often forgotten Sci-Fi author is Ted Sturgeon.
If your shocked at the price of new books, find a used bookstore.Many will take your old books in as trade. You can often pay as little as 25 cents per book this way. BTW, the bookstores around here consider anything over 6 months as old. You can get pretty much new paperbacks for nothing.
