SanDisk 8 GB Sansa Clip Zip MP3 Player GREY with 8GB microSDHC Card (Total of 16GB Storage)
I bought this to replace an old Creative labs 30 gig mp3 player and I love this thing.  It is awesome with audiobooks and plays everything I've thrown at it.  It is amazingly small and the micro sd slot makes it very functional.  It works great with audible too.  It is by far the best audiobook player I've owned.
