Yeah I don't like the way the rig sits when it is screwed to the bottom of the camera, it's offset to one side and that makes the rig more unstable than it has to be. I also didn't like their suggestion of mounting it to the cold shoe which could make the camera top heavy - those are just my initial thoughts but so far I don't see myself every purchasing one.
I use the JuicedLink DS214 Preamp (7.2 ounces) mounted to the rig with an adjustable ball head adapter. Set the angle to keep an eye on levels and volume settings. The Riggy line looks a little bigger but probably not that much heavier. I also mount it on occasion to the hotshoe - it does not feel unbalanced. The JuicedLink line is impressive for it's small size and build quality - it does exactly what the mfg. claims.
