Well, I've figured out that it won't cost too much to have extra bulk CDs made, and I can do jewel cases, inserts and tray cards through Oasis "short run" for about $1 a piece - so I'm going to do that after all. Those that want books can have them, but for some purposes it's good to just have the music with all the helpful information (bio, songwriters, track times, etc.) readily available.

Thanks everyone for the encouragement!
