before you post make sure your facts are straight. the power supplies are for the hc200's which is a reliativly new product. I think this is the case with any product on the market wether its a car or a control system. they did right by thier dealers by putting the products out there. if your not having issues from the hc200s, sit on the power supplies. if you make a service call t a clients house, do your diligence and replace it.
