is the word!
(I just wanted to say that )
Anyway read this thread :
You will find many answers there.
As for the other screens you found (like this http://retail.mini-tech.com/KM-7-in%20dash-sell.htm ) they're not vga or tsk.
The only vga in-dash motorized with imminent release is the Autonode's one.
Hope this helps...
