Initial DVD-1810 Portable DVD Player with 8-Inch Screen
Good picture, good value
Out of a dozen or so similar options, we chose this one for vacation travel, and a second DVD player in the house.  So far, so good.  The picture is good, the sound is excellent on headphones, and it runs fine on AC, 12 volt and battery power.  It is the value it seems to be.  No $90 car adapter like Panasonic, no overheating problems.  We couldn't be happier.
