There is one product that is sold legally here under the name Red Tek 12A that is supposed to work as well as R12. Has anyone heard of it?

That's exactly what you should NOT do!
R12 is the way to go! It will work 10X better than R134a. You can kinda/sorta make 134 work almost as well as R12 by adding extra electric fans, a bigger evap, etc., but why bother? Just go with the R12. It is more money, but it's worth it.
If you don't go with R12, try Freeze12 (you can buy it online). But don't go with 134a.
