I did some checking on the prices, and the players can actually be had for less than this program through OverDrive. Check out the following players on Amazon:
- Creative Zen Stone 1GB, for around $35 each (basic black, and several other colors); also at Circuit City
- Creative MuVo V100 1GB, for around $50
You'll find lots of Coby mp3 players for sale, often very inexpensively. Be sure to check the compatible devices page, though -- many of the Coby players do not work with OverDrive.
I am not recommending one over the other; you might want to choose based on the display options of the player. The Creative Zen Stone is low-priced, but like the iPod shuffle, does not have a display to show you what is playing. This might not be a big deal for your audio book listening patrons, or it may be!
Remember, 1GB is more than enough storage space for an audio book.
