CYBERHOME CH-LDV 700B 7-Inch Widescreen Portable DVD Player
So Far, So Good!
I also bought this Portable DVD Player on sale around Christmas time in 2004.  We have only used it maybe 5 times in the car on trips.  So far it has been working great!  It is easy to set up and use.  I got the one with the Deluxe Carrying Case included.  We love it.
