Yea I agree, screens are expensive. I am also going to get a screen very soon, as soon as I make up my mind. As well as on a budget since I quit my part time job, and am spending from my savings. haha.
This is thre screen I am looking at now:
Got the idea from this thread: Motorized In dash 7" TFT. This thing rocks!!!
Its pretty cool becuase it is motorized !!! Not VGA or no touch screen. But I don't thikn I am going to get a VGA one anymore, 1) due to cost factor and 2) becuase this one is motorized and its fairly cheap!!
And I think I might just buy a track pad like on laptops or somthing and put it on the space inbetween my seats.
