Hey guys thanks for all the input. We decided to go with a cheaper route to start and see if it works out. We ended up buying 3 headrest mounted tablet holders($13 each), 3 new kindle fire hds ($120 a piece!!!), and 3 pairs of headphones. So each kid has their own tablet and personal movie holder if needed. Amazon also gives away HUNDREDS of apps with the tablets if you are a prime member, and not crap ones, the really good educational ones, as well as some high end games. We moved movies over from our computer, and its really workign slick so far for only a few hundred bucks. Plus the kids can decide whether to play games or watch a movie, and no fighting on which one to watch! i've been fairly impressed so far!
