dont understand what you mean by cheaper. there are many points of views on the changing of the r12 to r134. many say r134 is not as good as the r12 and others say they cant tell the difference between them. mine is working great with the r12 son i am not fixing something that aint broke. they do sell do it yourself kits but you have to be able to remove all the old refrigerant. i have had shops quote me prices at about 300.00 to convert it.

Keep R12 as long as you can.
If you change over to 134,. you will notice a change.
I did my C3 and after 1/2 a summer changed back.
Found an A/C wrench, willing to do it for me.
Under table money, works out well.

Use Propane. R290. It's cheap as dirt. It's compatible with your existing mineral compressor oil. And, it's even more efficient than R12. Flammability is about the same.

I also need a recharge on the R12 A/C.  I found a heating / AC business that was willing to do it.  I guess I'm lucky...

Yes. There is a very cheap alternative. Propane. Or, R290. It's what they use in Europe and Asia.
No need to change the oil, orifice or filter/dryer. R134a requires a complete system flush as the compressor oil is not compatable.  The orifice is a different size. And, the filter/dryer needs to be changed. R134a has about 1/3 less heat transfer efficency as R12. R290 is even better than R12.
Commericial shops are not allowed to install R290. It's an EPA thing. I've done it on 3 different cars and it works wonderfully.  Before electronic detectors they used to hunt for R12 leaks with an open flame and later with a hot wire. And, Propane has an odorant (ethyl mercaptan) in it so you know when you have a leak. R12 doesn’t. It' s your choice.
