i think the scs unit is a personal choice you have to look at the pro and con of any procedure. i do not have the scs but my dad does, for him he didnt like it he had fallen and the leads came out so it was no use to him, now he is having it removed. i have heard people say it was great and then for someone else it was not. i cant give you any personal advice on the scs unit but i can tell you do as much research as you can so you can make a choice that is right for you. good luck and take care, michelle
