Cyber Home CH-LDV1010A 10" Portable DVD Player
Cyberhome 10" Portable DVD Player - CH-LDV 1010A
Best buy for the money.  Super easy to use, good color, sound is better with the ear pieces supplied.  Has AC and DC power cords.  Battery life is ok but only average of 2 to 2.5 hours of play time.  Battery cannot be charged while connected to player.  Consequently, you cannot watch the player when charging the battery since the power cords connect directly to the battery.  Cyberhome travel case is pricey.  Targus has model for about half the price.
