I went to RCOG in Atlanta Ga. The experience was very positive and in many ways unbelievable for both me and my wife. They do a combination of seeds and radiation with results published in medical journals that are equal or better then John Hopkins "Gold Standard" with less complication.
You can get more information and a DVD and booklet at

They track you every 6 months on everything from PSA, sexual issues and complications.
