I'd like to get one as soon as my wife gives birth. All I ever wanted was 2 kids, and she came with 2. She was determined to have another, and I wanted one of my own. Once the baby arrives, I'm also going to be looking at getting the snip. Oh, and I'm 24.
Back on topic though, you should totally get part off if they snip each bean. But if they do the main line, then I could see it being full cost. Maybe you could talk the doctor into having his plastic surgeon buddy give you a gift certificate for 1 free breast implant
