Good luck with your decision. Just keep researching and go to the seminars of the doctors you would like to do your Lapband with. I considered lapband myself but my insurance didn't cover it at the time(years ago). They cover it now. My surgeon's office hardly do them anymore but I had already changed my mind to have a RNY instead by the time I decided to have surgery. You hear about both successful surgeries and complications with all the WLS. It may help your decision to ask the doctor is how many of the lap band surgeries they performed have turn into a revision to RNY.
Good luck and I hope whatever you decide it turns out to be successful. I don't regret my RNY at this point. I just wish I would have done it sooner.
