Cheapest pro-am camera with live feed?

[pilotenorway]

Hi, I am seeking a camera which is to be used live on stage in theatre.
It has to look as an amateurcamera (small size) and have output a live feed.
Any tips?

 

[dop16mm]

For a play I would think an old consumer type 8mm or vhs-c would do the trick, they would all have composite out to feed a monitor or projector, and there would be no question that it was a home movie cam. Can be found cheap.
