We still have the right to designate who gets an organ that we donate when there is opportunity to do that. It is just illegal--for excellent reasons--to sell somebody an organ and no reputable medical facility would tolerate such a practice.
Cedars-Sinai Hospital is adament that Dick Cheney got no special treatment whatsoever--if money was a factor he would not have had to wait 20 months. At the time his new heart became available, he was deemed healthy enough to receive it, there were no people ahead of him that were a match. Try not to be too judgmental folks until you are on one of those waiting lists yourself. I recently lost a precious cousin who had been on the kidney transplant list for years, but each time one became available, she had other health issues that made it inadvisable for her to have the surgery. Until you know the facts, don't judge.
I won't presume to play God and say what Sarah and/or her parents should or should not have done. I can believe Sarah wants to live and wanted that chance. If it was my child, would I condemn her to die by refusing a lung when it was available? It is unfortunate that both sets of lungs that were made available to Sarah were damaged or compromised and nobody knows if the second transplant is going to take. She is still on a breathing tube today.
