Ah-kay's "willingness" is probably rooted more in necessity than in virtue!!!

That's precisely the type of argument that someone who doesn't have alll the facts would make. As a refrigerant, R-134a is significantly less capable than R-12. R-134a
systems work acceptably because they were designed to overcome the deficiencies of R-134a. An R-12 system does not have the advantages of the increased heat transfer capacity that was engineeered into the R-134a systems, so you cannot simply change the refrigerant type to a less capable version and expect good results. Any notion that you can simply defies the laws of physics.
For someone who is overhauling their a/c system, the added cost of using R-12 is small when compared to the overall investment being made. The payoff is an a/c system that will work well as compared to one that will be a marginal performer when the ambient temp exceeds about 85*F.
