A one gig card will hold any Audible book you might want to send to your unit. However, four gig cards are used commonly with the B.P. and some people are up to 8. You want, compact flash and just about any brand will serve you well. they've been around for quite a while now so the technology isn't cutting edge. someone's usually running one on sale.

My name is Monica, and I am a new Book Port user. I just bought a Book Port from a friend who was no longer using it. I have a question about buying flash cards for the machine. Can any of you tell me where to get a good price and which brands seem to work well? I'm a little daunted at the wide range of memory cards and have discovered that there are even different types of CF cards. I want to shop online and am just a little confused about which type of card I need since the descriptions like to talk about digital camera compatibility and whether a card is 3mm or 5mm in size. The card that comes with the Book Port I bought is 256 MB, and I'd like to buy a bigger card for it, maybe a gig or two so I can use Audible books comfortably. I'd appreciate any shopping tips you have to share. Thanks in advance. Monica Willyard
