$237 with shipping. They have adjustable posts to fit most vehicles and each headrest has a dvd player in them. I have the factory headrests in my LUX but I put a pair of these in my other vehicle and the install was about 20 min and they work GREAT. The games are a little tought to get working and the instructions are a little tough to read but you figure it out really easy. They come with a set of wireless headphones that work fine but I am thinking of picking up a set of Audiovox as replacements. The hook up of these is simple ground and power and each unit has a cable to plug into the other unit so you can have either one work as the slave. Kids LOVE them.
