Coby TF-DVD8500 8.5-Inch TFT Portable DVD/CD/MP3 Player with Swivel Screen
Great product!!
I bought this for my 3 young daughters to use on several long plane rides.  I had no problems with it at all.  It was easy enough for them to figure out without the need of a remote (something else for them to lose).  The battery lasted well over 3 hours on each trip.  This unit has two headphone jacks so all you need is a splitter in order to have 3 sets of headphones hooked up.  Picture and sound are great.  I highly recommend this unit.
