OK Ill be traveling soon, so I need to trade in my regular cd player. I dont know what to get now. I see three options: (1) a hard drive based player, like the ipod. (2) something like the Sony Mini Disc. (3) a cd player that can support playing MP3. Any opinions on what is best. I like three because I would be able to play cds and MP3 without converting all my regualr cd's. But then again they are kind of bulkey compared to the new MP3 players. Any suggestions.
