Found this one today. These prices are lower than the NOS cylinders on market place or even some of the partially used cylinders. Did R22 suddenly become unregulated?
R-12 at a good price would be nice. I converted my classic Pontiac to R-134A about 10 years ago after I used my last one pound can of R-12. I had purchased several one-pound cans of R-12 back in the early 1990's and it lasted for almost 20 years. The R-12 blew like ice. The R-134A is ok, but I had to put an auxiliary pusher fan on the condenser to keep the interior temps down.
The refrigeration industry is now fully on board with the scam. I use to have 3 cans of refrigerant in my truck. Now 9 and 4 more in the shop. It is insane. Go back to 12,22,502 make it illegal to vent and have some kind of quality standard on equipment so it doesn't leak so easy
