I'll just mention just 2 points and move on, as all this AC banter has been repeated numerous times in earlier threads.

#1 R12 is not difficult to find. (Mineral oil campatible w/R12 is. But thanks to fellow member, Mark DiSilvestro, I have finally found it at CarQuest).

#2 If R12 is so bad, why does Dupont have a contract with the federal government to continue supplying the US Navy with R12 for its entire fleet?
