It depends on how much control and everything you need.
You could possibly achieve it in a very simple fashion with just an HDMI Switch to switch the video between both of the cameras. If you needed camera control things could get a little more difficult.
We quite often use two cameras on an SX20, and use an Extron DVS-605 to create a Picture-in-Picture view from the two cameras. The standard camera control controls one camera and we use separate remote to control the 2nd camera.
