Don't waste your money. I was able to easily implant my own at minimal costs. WalMart has a do it yourself kit that is only $29.99, including the chip. I was able to do mine just standing in front of the mirror in about 5 minutes. It was the second one I did actually. I implanted the one for my wife first just to make sure I knew what I was doing. It was kind of a fun evening for us. We held hands, walked out of the house under the stars and looked up, knowing that we were now safely tracked by satellite. I know this will be invaluable information that our government will use to enhance our lives.
