PKD has some bad stories, but I think he has a lot of good ones. Electric Sheep isn't one of his good ones, I agree with that. I quite liked most of the stories in Beyond Lies the Wub. An example of a bad story of his from that collection, off the top of my head, is The Indefatigable Frog. That was pretty silly. I encourage you to give Beyond Lies the Wub a shot before writing him off entirely.
