So reading through some of the comments, I want to make sure that folks see the difference between the version I'm considering and the Lippert junk that seems to be the most commonly referred to. I've seen the Lippert system and wasn't impressed at all. The one in my link operates independently on each side. Its also quite a bit more robust than the comparable Lippert project. Yes, its slow, but the difference is less than a minute...
I have the SteadyFast system installed already, which does a tremendous job in eliminating movement.
