Probably more than $1200, but I'm quite partial to the S4+iCue+Scroller+DMXIris. My only complaint is that the iris takes about a full second to open and close. It's an Apollo EZ Iris I think. I don't know if other brands are better.
What is the application? What are they competing with? In that price range, with no other information to go on, consider a used Martin 918 or an HES Technobeam.
