Audiovox DVD1680 7-Inch Portable DVD Player
Worth Every Penny!
I have used this many times since buying it a few weeks ago and am very happy with it.  The picture is FANTASTIC!  Very clear and crisp and easy to see even in direct sunlight!  The audio is great with the ear buds provided - excellent virtual surround sound.  The unit dos get a little warm after a few hours, but so does a laptop PC.  I used it in a long car ride to Maine last weekend over very bumpy roads and it did not skip once.  A great product!  :-)
