Google Icon-TV, I can't remember the info off the top of my head. Their website has plenty of info.....
The 8 inch monitors on Ebay go for about 800 as well.....
I do not have another as I used it as a stand alone with a PS2 and TV Tuner...Had the screen mounted in a custom console off the floor in my old bonneville....
I can be a headrest monitor, but I cannot find another one like it, so I gave up...Been looking for a good 6 months, it will be best suited as a standalone mounted somewhere.....It does not have a built in DVD player.....It is just a 6.8" screen....
Specs are on their site, I don't know much about mobile video, so I can't answer why they are so expensive.
