Audiovox D1750T Portable DVD Player with 7-Inch LCD
Great Product for a decent price...
So far it has been a great experience, I conect my unit to the TV and I take it with me when I travel.  It is not a HD DVD player... so be aware of that.  In my opinion, for the price it is the smallest and lighter to carry of all portable DVDs with a very good screen and picture.
