My sister in laws cost her $ 7,500 including the 4 day hospital stay, anthesia and surgery. Her insurance covered some of the cost, her total out of pocket cost was $2,000. This included the removal of 35lbs of fat in addition to the stretching and removal of the skin and having a new belly button sewn in.
Recovery time is individual but she was told that she could NOT begin to exercise until after 6 weeks and that all the swelling would go down in about 3 months, which was about right. She had minor site healing complications, as where they did the tie in of the stiches is kind of hard but it can't be seen, you can just feel it. Her scar has healed very nicely. All in all she is very happy with the results.
Hope this helps.
