To answer my own question, I went out and bought a ST-E2 and it works great. It is larger than I expected it to be but alot smaller and lighter than a flash but I can now focus in almost complete darkness, something that the camera would not do even with Live View.
I have only tried center focus so far.
This is good news as I already have the ST-E2.

Does anybody know how much a new battery for this equipment costs? :dunno:
