Dell DJ and Samsung YP-910GS produce good-quality sound.
If you're going on a long trip--or if you need to have all your music with you all the time--you'll want a digital music player with lots of storage.

New players from Dell and Samsung have 20GB hard drives that hold hundreds of hours of music. I tried shipping models of the $329 Dell Digital Jukebox (aka the DJ--the company's first MP3 player) and Samsung's $399 YP-910GS, designed to work with the new Napster music service (see page 42). Both units play MP3 and WMA files and accept file transfers from Windows Media Player and from their default applications.

The DJ's default software, Musicmatch's basic version, rips from CD slowly but simplifies syncing the music on the player with that on the PC.

Nice one. I like the idea of being loaded with Napster.
