What I've done if I need AF assist in the dark is to take the flash off the camera and use the pop-up flash for AF. I use my OK button to focus, and the flash fires FA pulses to help it focus. Then I push the flash down and fire away with good focus.
It's rare that I've needed to do this, but it does mean that I'm not dragging along a flash just for AF.
