I'm like you, I like to research and find out all of the information that I can about a procedure. What I've found I need to keep in mind when doing that is that usually, now that's usually, only people whom are unhappy complain about a procedure / outcome. Those folks for whom it went well have, for the lack of a better explanation, have moved on. They don't come brag about how well they are doing, which is a shame.
So to to keep an open mind when doing your research, as I'm certain you've been doing.
