Science Fiction?

[master0ffear]

So I've gotten myself into a huge science fiction kick from reading Kurt Vonnegut and watching Doctor Who. I volunteer at a nearby library during my vacation time, and I keep kicking myself for not snagging some of the 1970's sci-fi anthologies that were donated [ they can't sell anthologies, but I guess I wasn't thinking].

Since I'm a bit of a thrifter, any books I go out of my way to buy will probably be at a thriftstore/usedbookstore/library sale. But if anyone could rec some great science fiction please do!
