No matter what procedure someone decides to do, by far the most important thing is the SKILL of the doctor. There are a lot of good doctors throughout the country but the real experts are harder to find. If you search the internet or subscribe to some of the prostate cancer forums:

http://www.ustoo.org/Treatment_Options.asp
There is a wealth of information on these sites on all types of treatment of prostate cancer as well of mailing lists of responses from those that have been treated.
Personally, I was diagnosed five and half years ago, and treated by radiation seeds and external beam radiation at Dattoli Cancer Center in Sarasota:

My followup care is being performed by Dr Charles Myers, Medical Oncologist specializing in prostate cancer and a ten year survivor himself:
