I have a Freon leak and if I could get enough R12 at a reasonable price this would not be an issue. The problem is that I have heard that If you convert to 134 with out replacing all the o-rings, Hoses and Condenser that the higher pressures and corrosives of 134 will eventually lead to more leaks.
I would be willing to pay up to $40 per lb for R12 but much higher says that 134 makes sense

What do you guys know that I have to learn before repairing this leak
