I'm looking to buy a portable CD player - the equivalent of the Sony Walkman that plays cassettes - and I have three primary requirements in mind: 1. Ability to play CD-Rs (music, not data) 2. Skip protection (absolutely critical, as it will be bumped often) 3. Good sound - not flat or tinny sounding. I'd prefer not to spend a fortune, but am willing to invest a reasonable amount, as it will get a LOT of use. Thanks in advance for any feedback y'all can give.
