Mintek MDP-1770 7-Inch Portable DVD Player
This item is great
If you are looking for a really inexpensive portable dvd player for a young child this one is really great.  It is easy to operate and it has just enough features to allow them to use it alone.  My son is four and he loves it!  He takes it everywhere.  This player has a good picture and quality sound for the price.  If you are looking for more, then pay more don't expect this dvd player to be more than a nice accompanyment for a child or teenager.
