To answer your question about 20 orders, that was only a starting point. More people can join in. As I explained earlier, before I finalize this deal, I want to install the set I have coming to which I will detail installation, finish, fit, and adjustablility. On a down note, I haven't heard from Dave in several days and I am getting concerned. I can't call him because the only phones I have available are company phones and I think my work might question a call to South Africa. The bottom line is that nothing else happens until I see how these things work out, I am just a little annoyed by the lack of communication. He says he currently has 7 Black and 6 Silver sets on hand, I am waiting to hear back as to how long it will take to make the balance.
