Over a hundred views and no reply. I must say I am not surprised. At least once a year someone asks the same question and they have received the same lack of reply. I know several people who have them...one even has it hanging on his garage wall. In my case, to save what is left of my system, I took it off and installed the one developed by Richard Clark. But I need to keep it...it was carefully removal so it could be reinstalled if desired.
If you are really interested, why don't you shake the tree by throwing out a number, say $4000 and see if it knocks one of those systems off the wall.
