Harlan Ellison Books

What is the best way to acquire readable copies of Ellison’s short stories?

Amazon prices look extremely high at hundreds of dollars per copy. By readable, I mean books with font sizes larger than size 6 so a probably editions published after 1990. Is there a better name for these readable non-1970s editions?

eBay and thrift books are also good alternatives.

I guess I am surprised prices are so high but I guess many of his books are out of print.
