I would not want to risk ruining my or anyone's eyes through the use of the laser based AF assist of the YN-E3-RT.

Really a laser?  I have the 600ex-rt; it has a good, solid AF grid, maybe not as bright as the 580ex, but I'm sure it isn't a laser. 

Maybe just seems bright relative to very low light?
I'm sure the Yongnuo transmitter uses a laser for the AF assist. It is very bright and the dots have this laser-only speckle pattern.

If you haven't seen it already, you may want to take a look at the Yongnuo YN-E3-RT: http://www.amazon.com/Speedlite-Wireless-Transmitter-YN-E3-RT-ST-E3-RT/dp/B00H7XFOKO

It is a clone of the Canon, but includes a AF assist light. There are generally pretty positive reviews but a few here and there pointing out a few disadvantages, namely slightly lower build quality. But for $90, it's a killer value.

Also, the AF light is not perfectly centered with the FOV. It's strange, but look at some of the reviews demonstrating it.

I just bought a new 600EX-RT and needed a transmitter.  Decided to go with the Yongnuo for exactly that reason - the AF assist beam.  (Well, that and the fact it is a fraction of the cost)
These days, I sometimes expect to see Rod Serling step out of the shadows and point to a signpost up ahead!
