Audiovox D1708PK 7-Inch Ultra Slim Line Portable DVD Player with Bonus Pack
Just Right
I just purchased this and am thrilled.  It has all the things a parent could want ie: two headsets and jacks, decent picture, good sound, the car kit and the adapters.  The ability to play music and movies, the audio/video inputs and outputs to play games or hook up your video camera for a mobile slideshow will come in very handy in countless situations. We tested it out at home and found the player to be sound and I'm happy with the choice.  I did notice the headphone volume doesn't go up very high.  It was right where I would put it at max volume and not be blowing out the kid's ears.  I think that is a plus and not a minus.  I'll have to test it with road noise...I guess it depends on your car as to how this will affect you.  If it is a problem, there are headsets that have their own independent volume controls and each person could boost the volume to suit their needs.
