I'm looking for suggestions and recommendations for adding video... a little info about how it would be used... typically, to keep children (8-12 years old) entertained on trips. Would like not to spend too much and am reluctant to make modifications to the van myself - not really a DIY. I sort of like the "bag" type systems but wonder if they hold the monitor/screen high enough to avoid car sickness over time... not sure if the backseat theatre, that requires attachment to headliner plus has a transmitter for the VCP signal, has real good picture quality. But $1,000 and up is too high to spend right now for something that will only be used every so often... ideally, would like a "bag type" with a decent sized screen if it holds the screen high enough. Thoughts? Where is that best place to buy?
