if anyone is thinking of being cheeky and getting an mp3 player to use as essentially an external hd for use with Serato the only way to go is a Nano because hd based players are to slow.... just something to consider also,. ive had a zen touch 20g for the last year and havent had any problems, I picked it because it was rated to have a longer betterey life (at least compared to the ipods of a year ago, i have no idea what the new ones are rated at), and for the software, which i really like (i hate itunes though).
