which monitors are good?

I am selling my 95 Impala SS seats this weekend which have headrest monitors in them and now I am going to be getting a flip down to replace those so my 2 kids dont drive me nuts. I already have a Kenwood 7" Flip out up front so I think Im just going to get the screen with out the dvd player How do you know which ones are good? What resolution should I be looking for? What does TFT stand for? Im not looking to get a cheap one but I dont want to spend a ton either Any info would be greatThanksBernie

One more question. I am kind of a Kenwood nut. I have the head unit w/ 7" flip out and just found that I can get two 7" flip down monitors for a decent price. Whats everyones thoughts on 2 7" flip downs instead of one 10.4 flip down. These will be mainly used by my 2 kids one 3 the other 2. Wouldnt it be better for them to look straight ahead instead of head have twisted looking at one monitor in the center of the car? Just a thought. Let me know what you think. LaterBernieBernie
