It looks like with the audiobooksforfree site you pay according to the quality you want - you can get low (but presumably audible) quality for free, or choose to pay a more and get high quality - the higher the quality the more it costs but doesn't seem excessive. They did have some recommendations about MP3 players for audio books on the site - it seems that not all of them work for audio books so you have to be careful when choosing. Some don't allow you to return to the point you left off. I'm glad I enquired before just running out and purchasing and MP3 player.
