GoVideo DP7240 Off-Road Portable DVD Player with 7-Inch Widescreen LCD
GoVideo DP7240 -- Good All Purpose Choice
I own this portable DVD player and really enjoy it. 7\\" screen is sufficient.  (I would not recommend buying a smaller screen.) Picture guality and sound are both very good.  This portable DVD player feels more substantial and less fragile than many on the market.  I have no complaints.  There are better portable DVD players on the market, but you will pay much more for them.  This has to be one of the best that you can get for under $300.  Battery life is a little less than advertised (as with all portable DVD players).  I get just over 2 hours from the battery before it needs recharged.
