If your buying tvs then look around!!
NECVOX, TVs are the best 4-13" LCD monitors(TV's) ive used for installs, centurion are expensive for what they are as there viewing angle is limited, the necvox units have a wide viewing angle, smaller over all size ie from edge of screen to edge of unit, and they are slim and can be flush mounted easily, with adpater that comes with them.
They start at £130 - £1000 about £135 for a decent 5.6" unit, and £450 for drop down, ive got loads in my car if any one wants to view them!
