iPod Compatible Travel Soother 20 Radio/Alarm Clock (SI721SIL)
For a personal radio, it's great!
I used this radio on a trip for 7 days, used it every night and on the beach during the day and the batteries never ran out!  For a little radio / soother, I thought it was wonderful, just a personal radio.  We never expected surround sound quality from it.  In the hotel it blocked out the noises of the hallway just fine.  My kids listened to stories from the iPod plugged into this radio and it kept us entertained for hours and still sounded great too.  Do take a huge note that this doesn't come with the  AC adapter to plug into the wall (SM917USA).
