Thank you for taking the time to make such a long post in response to my message, I will check the websites and also wait to hear from others on what they have to say. I want to take the time to make the right choice so like you said I won't have to fix it later. I was told by a retired dentist that high end gold was the best but I am concerned with meridian energy. I will let you know what I decide on and how it goes.
