Audiovox D1812PK 8-Inch Portable LCD DVD Player with Car Kit
Highly recommended!
Bought it for the kids to use while traveling Thanksgiving weekend. The car kit with case is convenient and packs well, and was no big deal to carry through airports.  The remote and unit controls are well laid out and easy to use.  The picture quality when watching animated features was more than adequate.  DVDs loaded quickly.  The battery did not run out over a bit less than 2 hours of use.  The included folding headphones are cheesy, but provoked no complaints.  There are not 2 audio jacks built into the unit - an adapter is included instead, and functioned without any problems.  We also used the included a/v cables to connect the unit to a television, and it functioned great as a DVD player.
