My mother in law has had the band. She swears that it is the best thing she has ever done. I cannot speak from experience, but from what I understand there are fewer complications with the band and it is easier to reverse if required.

You have to be a member to view these forums, but as I recall, there were a lot of members who had had various methods of weight loss surgery, and there is some really good, comprehensive information. At the end of the day though, it has to be your decision.
Good luck!!
