Does anyone have either a flip down dvd player or the dvd players in the headrests of their car/van/truck/suv? If you can you please tell me the pros and cons of them. We are looking to get one or the other for our dodge sport caravan for long trips that we take with 3 kids under the age of 8. If you could please also state how much you paid for it, where you got it from, and where you got it installed and the cost of the instillation. Thanks!
