I have the MP3 Jukebox 100. It's great. I use 192kbits/second as the compression rate. The standard is 128. Some of the better recordings I go up to 256. I use this with the "airhead" amp and etyomatic headphones. For travel, the convenience and quality is tough to beat. I have found this player to actually sound better than most portable CD players. It does have a lousy amp section though--you need to get one of headroom's amps to go with this.
