Polaroid PDV-0700 7" Portable DVD Player
Pay your  money, take your chances
As the other reviewers note, when it works, it's a pretty good player.  But, the odds that you get one that works over the long haul is probably 50-50.  We've been through two in less than 2 years.  First one had the power supply connector go bad.  The second one loss the picture.  Not about to buy another one.
