Saved my butt again just yesterday on a 5:30am SRT8 run from BWI airport to Washington National to rescue my daughter and her boyfriend from the evil clutches of USAIR and preserve their spring break vacation, a worthy cause if I ever heard of one. As my daughter said..."Dad, we need one of those "Air Daddy" runs to make it." Running down 295 through the National Security Agency Federal Area in the dark with a Federal Police Officer trying to get me from the rear, no fun if THOSE guys tag you. The old rear arrows lit up and saved me big time. He comes flying by and nabs a riced out VW who obviously was running without protection and who gave me a WTH look when I abruptly backed off causing him to fly by.
By the way those things are upgradeable by going to Valentines site and putting in your serial number and they quote you a price. Hard to imagine there are too many used ones around.
I will buy yours Zen if the original poster does not take it and you still don't want it.
