R134 AC conversion
So I'm thinking about taking the opportunity to convert my AC on my 89 s5 to R134 while one of the lines is being re-built. It's my understanding all I need to replace is the drier and the fittings for the high and low side where the pressure valves are, is this correct? I'm really only thinking about it because the R12 is about $60/lb right now, and I believe the RX AC system takes around 3-4 lbs... Has anyone done this? How did you like it? Did it cool well enough?

The best possible solution I've seen is to get some freeze-12 from ebay, or buy some r12 from a friend who lives in a country that still sells it, and put it in after checking for leaks. R134 conversion is seen as merely a hack in our cars since we don't have the space (or the proper components) necessary to run it well. I see you are in Arizona, so I really wouldn't recommend converting unless you've got some one who really (really) knows what they are doing.
Here are some helpful threads that I've come across in my own searches.

I wasted like $40 bucks trying to R134 it.. failed.. Then i man'd up and went with a Freeze 12 complete kit on ebay... Replace the drier before you do.
I think my system would benefit from a efan on the a/c condenser to help chill it *or i gotta work on ducting*, but other then that, freeze12 is the way to go.
