Howdy, Proloxic!
I'm reading The Complete Robot right now. It's a collection of Asimov's short stories on robot themes. It's very good.
You might be more familiar with Dick and Ballard than you think.
Philip Dick was an American SF writer circa. His stuff was
published from the early 50's to the mid eighties (then he died). He wrote a lot of stuff. I have read about half of his short stories and a third of his novels. I've read almost all of what is considered his better work, and I'm working of the rest. A lot of his stuff is coming back into print.
Minority Report, The Imposter, Total Recall, Blade Runner, and Screamers (I haven't seen this one) are each based on a Dick novel or short story. I think Total Recall is closest to the feeling of a Dick story. There is a lot of adventure, a femme fatale, sci-fi elements like androids and psycic mutants, confusion of realities, ....it's all very outlandish.
However, his characters usually lead very mundane lives and the outlandish environments and situations mirror our own, (that's the beauty of great science fiction). He uses the trashy sf novel as a vehicle for his own philosophical ideas. Some of his favorite themes are: Defining Humanity, Insanity, troubled relationships, the failure of beaurocracies, the danger of fascism...the list goes on and on, but these are very common in his stories. Also, he writes a lot about Mystic religions, although they have a different face everytime he presents them. (Hero with a thousand Faces-Campbell comes to mind?)
I reccomend his short story collections. I'm reading volume 2 right now, it has the story that Total Recall was based on. It's very good so far.
For novels try:
Ubik
The Three Stigmata of Palmer Eldritch
Do Androids Dream of Electric Sheep (Blade Runner)
He's my favorite author. I've become addicted to SF because of him.
