I decided to do 134 because its more likely to be readily available in the future and with replacing everything I had the opportunity to do a proper conversion. My A/C is ice cold and comparable to the A/C in my w140 even though the w140's system is a superior design.
I think a lot of the misinformation about 134 is due to leaky systems that people just put a charge on without completely sealing and cleaning the system. The unfortunate truth is if you want really cold A/C your going to likely need the assistance of a professional that's able to correctly seal your system and get any moisture out of it with a vacuum pump. Pumping 134 into a leaky system with moisture in it would have a similar effect to doing that with R12.
People who willfully pump R12 into leaky systems because of cost are the reason why we had to change to 134 to begin with. Karma is a wonderful thing though. That moist sort of cold air must be great eh?

You got sold a bill of goods, man! R12 is still being produced overseas, you just can't make it in the US anymore. The whole "it's going to run out" in the future thing is total B.S.
And R134 isn't any better for the environment than R12, it's also highly toxic. I'm not really sure what the government thought they were doing when they started forcing the switch. In any event, the government has really backed off the whole R12 ban thing anyway, they don't seem to care about it now. It takes 30 minutes to get a refrigeration license online and buy and install it yourself. All the a/c shops around my area have no problem dealing with it either.
