Initial DVD-9510 Portable DVD Player with 4-Inch Screen
I really like it!
I bought this because I have a small car and 2 young boys.  I have been very happy with the performance of this one.  The picture quality has been great as far as I can tell and there is certainly no problem with the sound. The only complaint I have is that it does tend to get pretty hot.  This has not been a problem so far because our trips have been under 2 hours, but I wonder how it will perform on longer road trips.  For the money though I have been quite pleased with it.  The battery pack is great.  I love the fact that if we loose power in the house, I can still pop in a DVD when all else fails to entertain.
