Ok first post don't flame since I have extensivly read the archives and lagged the server with searches

anyway here is my situation
- 400$ for a miniature vga screen is completely out of the question... don't even suggest it ;\
- sadly i do not have the ability to wait the time it would take me to save for a 'proper' vga touchscreen..
- i can get either a 7" composite screen (pyle, pyramid, legacy, lilliput from HK) for the same price i can get a normal used 15" pc stand alone monitor.
but i have a problem.. between a blurry image and a huge screen i have little choice. if i go with the 15 i will have to mount it either on the foor basically right next to the center console and shifter reducing my passenger area and probably getting it in my way or mount it on the glove box at an angle facing me taking less space off the floor. Both ways will be non permanent or vehicle damaging so that is my concern i guess once i get to it.
now my uses will be anything and everything and i am leaning towards productivity above all. obviously i don't want to look rediculous with a cinema view in my front area and passenger seat space is not really that important to save.
so, anyone chime in. i guess i am basically asking if i will look like a moron for a huge screen or if i will hate myself with a blurry useless one. i have to decide and choose the lesser evil.
