Duponts patent rights will run out on the 134 at the end of this year.
Seeing as they curretly are the only name on the block, they plan on
reaping the max profits prior to the brand -X mfg's making the 134
available.

Right now Wally world is having a sale on the retro kits for $7.99

Better load up if the lower output temp and higher operating pressure
134 is you bag.

Time to start looking at the R-12 A's benifit's, and inexpensive
pricing.

I know.

It doesn't work.

LOL.

<<Subject: A/C Work just got more expensive
We all know that some time ago R-12 was deemed a contributor to the
"Green house Effect". Whatever your beliefs in this area, the result was
a ban on the manufacturing of R-12 and the introduction of R-134a
(supposedly a less harmful substance, however that is up for debate
also). Anyway for the last ten years or so we have been happily
converting our Vans and other vehicles over to the "cheap" R-134a. It
has indeed been cheap at under $5 a can in Walmart. However this summer
you will get a suprise. Over the winter the cost of R-134a (our cheap
buddy) has gone up over 400%!!!>>
