I bought the "Movie Advance" from some online Hong Kong store... the thing is great!!! I bought a 1 gig flash card to go with it and now I can watch movies that I have ripped from my collection, shows that I have on my Tivo, read an ebook, listen to MP3s, or play old NES games.... I highly recommend the device.
Right now on my player:
Master and Commander
The Godfather
Home video of my 8th month old ( she is sooo cute

)
about 4 CDs worth of music
a couple of ebooks
pictures
and about 20 NES Games
