I too liked Waystation. But I found Simak's other works just didn't grab me, though I liked his kind of sad writing tone.

James Blish Cities in Fight was a classic. A real blast.

I though Philip Jose Farmer was very good. I appreciate we're moving beyond "classic", but I'd consider him classic. Obviously the Riverworld was popular and good. He kind of kicked off that whole using historical figures as characters. But I think his World of Tiers was better. Very inventive, and a rollicking good ride.

And Jackl L Chalker Well World sage. That was awesome.

I read all these books as a kid. I think one measure of a really good book is if you still enjoy as much as you did when you read it as a kid.
