I actually went to a plastic surgeon last year and got a quote on a breast lift and augmentation with a belt lift (a tummy tuck and @ss lift--they cut you all the way around instead of from pelvic bone to pelvic bone.)
I'm not sure if you seriously wanted a $number, but I was quoted about $25k for all three procedures. We live in Minneapolis, MN so that could be completely different where you live.
I WILL be having this done when we're done with having babies. I told DH he can just forego the jewlery "push presents" and get me that when we're all done--although it's kind of a gift for him, too, if you think about it. ;-)
