Portable DVD

[Centerfire]

Hey .. need some input.... Thinking about gettinga portable DVD player for my Son for his little girls a to view on road trips to the other grand parents etc.. Needs to be portable as they may take either vec.. Usually my Daughter in laws Honda CRV sometimes my sons GM Truck..

So anybody have a history or experience with any of the units... All comments welcome.. & hell no I'm not putting in an overhead system in both their vec.. Not after the playhouse and pony cart and misc other spoit the grand kidd stuff awaiting Santa Claus

Thanks
