Audiovox Portable 9 Inch Portable DVD Players??

Portable DVD Players?? - audiovox portable 9 inch

Has anyone bought one player each Audiovox 9 "portable DVD player? Looking to buy a portable DVD player for my son, you can employ while driving. I've got a good deal for Audiovox 9" but I'm not sure what quality is. So if anyone knows anything about this or it would be better to have a portable DVD player that I can attach header please let me know!

Thanks
