I've had the Touratech ones on the bike for a few years.

They have been used to carry 38L ZegaPro boxes and they have no signs of cracks, breaks or bends. They do mount in three places and have a stabaliser bar at the back, so they are well put together.

I've had a few off-road incidents with then and they don't appear to be any of the worse for their experience. Yes, they are expensive, but the racks are the 18mm loop type that some of the soft luggage manufacturers are making mountings for (Kriega for instance). I wouldn't be surprised to see this type of mount become something of a defaco standard over the next few years.

As an improvement, I would think something that uses the two top mounts on the bike (the ones the OE pannier racks use) AND a third mounting to the point at which the rear hangers mount to the bike would be good. Today though, the third mount fastens to the rear hanger itself.
