Have You tried listening to the new Microsoft / Project Gutenberg audio books? I find 2 faults with them: 1% of the time I can tell it's a robovoice narrating the MS/PG audiobooks, and When the book switches back and forth between multiple speakers in a conversation, the MS/PG audio book fail to change voices enough. I have spent a week downloading most of them, and will continue to leech until I have to whole 1.25 TB collection with a back-up copy.
