If you are in FL definitely Dr. Reed. He is also one of the cheaper ones, and one of the few that is a Urologist. He is old but he is very good. He did mine 20 years ago and it came out great.
He operated on me a year ago or so for something else and his age was no issue. Several doctors have commented on what a clean job he did on me recently.
FYI if you want Erect gains you need to commit to about 8-10 hours a day of stretching for a year or more. If you do it half-assed you wont get much of an Erect gain at all - or nothing really. I gained 1.25\" Erect but you really need to commit. I could not do it today but I was much younger then and cared more.
I have had a good experience with dr Solomon in Philadelphia, check out my thread. I can\'t speak of results yet since I haven\'t begun Hanging. He does not use the \"silicon thing\" as call it though... But I believe he has a lot of experience in the domain, but he is pretty expensive.
