" I have converted all of my freon A/C automotive units to R134. Here is
" the differences that I have noticed. 
" When the outside temperature gets over 95 degrees the 134 units just
" keep right on cooling. At 100 degrees the Freon units were straining
" their little poopers to blow cold air. At 110 degrees the exact same
" unit will blow ice cold using 134. There will be a tendency at a stop
" light for the air temperature to get warmer but as soon as the car is
" under motion the air temperature begins to drop again. I have no problem
" using 134 and have found on the whole it cools better than freon.

" you can't just empty the r12 and recharge with r134,
" SNIP
" Sonofagun, I did not know that! 'Cause that is exactly what I do! Well
" actually about 4 years ago that was the urban legend involved as freon
" started to disappear but in this area there are a whole lot of extremely
" knowledgeable A/C guys that deal with automotive A/C quite regularly.

well, i learned something in all this discussion.  one nit though:
both r12 and r134a are 'freon', a dupont umbrella trademark for
fluorinated hydrocarbon refrigerants.  there are many others too.
