Recent Dr. Marchesini or Dr. Rabkin experiences?

Another option for you might be Dr. Ungson in Mexico (the only DS surgeon in Mexico any of us would recommend). What his rates would be for going from sleeve to DS I don't know, but he's reasonable for the full DS and has a great reputation.

Dr. Marchesini did my virgin DS surgery last year and I have not had a single problem other than being gluten intolerant.  He is an outstanding person and doctor and I wouldn't hesitate using him for a second.  I lost below my goal weight in 9 months but that varies by individual.  I was self-pay and my total 2010 cost was $19,000 for two to fly round-trip to Brazil and stay two weeks including hospital, hotel, surgery and food. 

I do not have any personal experience with Dr. Rabkin but know he is also highly regarded.  Either way you have two great choices.

Good luck!
