implants???

Anyone had any real problems with them? Ive seen the sites where they show problems and all but how often can that happen REALLY?? And saline vs silicone gel (new!!!)?? Any advice will be greatly appreciated. I DO WANT THEM THO...only cuz I they arent as pretty as they used to be after child birth...so Im not lookin for Pam or Dolly ...just a little better then what I have. thanks
