A few weeks ago I had to get a new house AC condenser-compressor unit. Fortunately for me I had about half of a 30 lb cylinder of R22 I bought in '92-93, so using my own freon saved me a couple hundred $ at today's price. I mentioned to the AC guy that I had some R12 stashed away too. He said so did he. Stuff's so seldom used any more R12 is not worth much and there's very little demand. He said R134A works good enough in older R12 equipment there's just no demand for R12.
