Panasonic DVD-LV50 5-Inch Portable DVD Player
Good dvd player
If you just want a DVD player, this is perfect.  Good sound quality and image.  One caveat, there is no audio/visual INPUT, only OUTPUT.  So you can hook it up to your TV to watch a movie, but you CANNOT hook up a camera to it and play a video from your camera on it.  With some of the more expensive models, there is a/v input that allow this - which is a nice feature.
