Audiovox VBP-2000 Video-In-A-Bag with 5-Inch LCD TFT Screen
Worth every penny!
I bought this product for car rides and to watch videos in hotels and on a cruise ship.  This is a terrific product.  We use it in an suv and a small BMW sedan and it fits fine in between the front seats.  My son sits in a booster seat in the middle and it is no problem.  It sets up in minutes and tethers tightly to the seat framing.  The picture and sound are perfect and the unit itself feels very sturdy.  We originally bought the 4 inch but exchanged it for the 5 inch when it went on sale the next week.  The 4 inch was ok in the car but the 5 inch is much better for using on a table top.  If you take long car rides or stay in hotels regularly, this is a must have and the Audiovox is by far the best on the market.  It folds up in the backpack provided and can be carried anywhere.
