Audiobooks by Zelazny

I’m a big fan of Roger Zelazny’s work and, while I have print copies of most of it, I don’t have any audiobooks of them. Do any Dopers know if such things are still available (I’ve seen old web pages for cassettes of abridges version of his Amber books, but have been told that those are no longer in print) ? I’d prefer unabridged to abridged and downloadable to CDs to casstte (I don’t even own a cassette player any more), but beggars can’t be choosers, right ?

Thanks.
