Initial DVD-1810 Portable DVD Player with 8-Inch Screen
Great Player
I just purchased this player off of Amazon.com about a week and a half ago.  So far, it hasn't had any trouble.  The picture is great, the sound is good, (great with headphones).  I love that it comes with a car adapter, and many other things.  Some cons are that the battery only last about 2 hrs, so it wouldn't be much help on a plane.  Also, the top of the part of the dvd player were the cd is put can bend open while it is closed (try to understand what I'm saying).  Overall, this is the best dvd player for its price range.
