Audiovox D1500A 5-Inch Portable DVD Player with Car Kit
Durable and also a great value!
We rcvd this as a gift for xmas.  Not only does it have endless options (battery,Cigarette and A/C adapter)it allows you to take it anywhere and stands up to the test.  We have taken it on bumpy roads in the car w/o skipping, and my 2 yr old has even tossed it on the ground and gotten COOKIE in the player.  No big deal for this machine.  It is a bit bulkier than others, however, it's still compact enough to not be a bother when travelling.  With 2 small kids...I need entertainment on the fly and this one works.
