Hi I too started looking into lap band surgery 18 months ago and am self pay. I decided after countless hours of research, calling doctors, asking about complication rate etc to go to Mexico. I am going to have surgery in August. I personally know 2 people that have had surgery with Dr Aceves in Mexicali. Look around on the forum under doctors. There is a wealth of information there as well as what you should be asking before you pick a doctor.
Good luck on you journey.
