Must be something about the SE area and the Diamond Shield and similar products. We have been shopping for a while and every used unit we looked at with the DS stuff looked like crap. I told everyone of the salesmen that it would either be removed before we purchased or I was expecting a $1,000 of the price.
We ended up buying a new unit and they offered to install DS I told them if they did, they would be taking it off too.
