I was in search of R-12 replacements since the subject came up recently, and have found what appears to be a drop-in replacement that can actually be more efficient than R-12 called R-406A. It sounds pretty good from their web site materials but I have no experience with it. You can see what they say about it at their URL: http://www.autofrost.com Anybody else ever heard of it?
