Hi all,

I don't want to start a holy way here, but I was wondering if anyone knows
the current "best choice" for AC refrigerant upgrades.  I have read the
archives, and I see that Ken Wilford was very happy with Freeze-12.  Ken,
are you still happy with it?  Then there is R-134a, pay $$ for good old
R-12, and finally Autofrost.  I won't consider the propane or butane
replacements.  I wonder about the legal, performance, and availability
status of some of the alternatives.  Some things that might effect my
decision:

1:  I will be replacing my compressor.
2:  My receiver / dryer is only 3 years old -- I'd like to save it if I
could.
3:  I really don't feel like changing all of the seals, but I could.
4:  I have one other car with R-134a.  I suppose I could stock up on it
while I can still buy it.  How long can you buy it over the counter?
5:  Is that epa license for $20 to buy Freeze 12 still for real?
6:  COLD!  I want it COLD!   I hear conflicting stories about R-134a's
performance in a system designed for R-12.

Any strong opinions?

Thanks,
Michael Townsend
