Hi, listers. I am a new Bookport person and am thoroughly enjoying it. I would like to purchase a set of or an external speaker for times when I don't want to use headphone or earphones or ear buds with it. have any of you purchased speakers or a speaker for the Book Port and if so, which speakers or speaker, and how much do speakers cost? Should I get the speakers with the amplifier built in? thanks so much. I'm really enjoying this list as well. Margo and Elmo
