Deals are always changing and the best place today may not be the best place tomorrow to buy an In-Dash DVD. If you were to buy yours today where would you get it from, too include fit kits, etc... Multiple vendors are okay.
In addition to where you would buy, I am also interested in why you like yours and if not what would you get? What I have in mind is a JVC, Pioneer or Kenwood. I prefer bluetooth and iPod control from the head unit; I don't need navigation.
