'97 Honda Civic, monitor suggestions

Hey everyone, I normally post on the audio forum, however I think Im ready to finally put some video into my car.  I have a 97' Honda Civic with a Clarion DXZ835MP HU, and I wanted to put a monitor at the top of my dash just above the AC vents.  I have a modded XBOX that I would connect to the monitor, and pretty much use that for all my media.  CD's will be played through the HU. I am looking for a 6.5-7" monitor that would be open to future additions if I decide to add navigation.  Touch screen would be nice too, but Im not sure how much of a price difference there is. Any ideas for a monitor that would fit this description and stay within 300 dollar budget?

any ideas guys? Even just the brand names of the better monitor companies would help....
