The DVD player is pretty thin (for under car seats), pop-top. Very durable, it's in my car right now. The screens are not motorized at all...
I'm not sure what you mean by decent quality...I think that some 3rd brand electronic items are better than their brand name counterparts. I can promise you that these are very nice items, and very strong items. They are just too much to have inside a tiny-assed Honda Del Sol, and I don't want them to go to waste.
I was suprised myself when I saw the quality of them. Besides, I am only looking for $200...
