Audiovox D1812PK 8-Inch Portable LCD DVD Player with Car Kit
Best 200 dollars I ever spent.
I bought this unit at Sam's club and did not have high expectations after reading all the reviews for the ones costing 3 times as much, but I was taking a cross country trip and wanted to have it to while the time away.  It was great!  I'll be honest, it is hard to hear some dialoque on airplanes, but I think better headphones would help.  I decided to play foreign films so I could read along with the subtitles and that solved that problem.  I watched one and a half movies on a trip from Raliegh to LA and it was the nicest time on a plane I have ever had.  The pictures is amazing, and if you aren't on a plane the sound is great.  When the battery dies (after about 3 hours), it makes a horrible sound, and the games included are loud and archaic, but I didn't buy it for games, so I don't mind.  I really like this system and it was a great price.  I bought a year long extended warranty just in case after reading the reviews.  I've had it a month and have seen about 8 discs on it.  I love it. I figure if it lasts 2 years, I have more than gotten my money's worth.
