Recovering R-12
Due to compressor problems, I need to remove the R-12 from my AC system for repairs. Unfortunately I'm having trouble finding anyone locally that still deals with R-12. Anyone here have any DIY experience with this (and I don't mean venting it)?

Any NAPA service center SHOULD be able to handle it, or any other national chain should be able to help..
Here is one in Norwich..

Not sure who you have been calling, but can't any of them recommend anyone local to you?

Many do not want to handle R12 because it may be contaminated, dirty, include freon leak detectors or mixed. The freon recovered, if virgin, still needs to be cleaned and filtered. I do not know of any local shops that "buys" used freon. The service fee may be expensive. Recover & refill.
You mentioned the compressor needs repair. I attempted to reuse my compressor and within 2 weeks I replaced the compressor with an eBay rebuilt $230-my coil failed. This caused double the work to flush complete system twice, 2 dryers, double the "O" rings, compressor oil and freon.
This does not answer your question but I use it for AC information.

Most shops around here will "store" your R-12, for re-use in your system, but they won't outright "buy" it for general stocks. As part of this they will want to do the repairs to your system, but sometimes you can work a deal.
BTW, my son is a big proponent of Freeze12, while I have been critical of it. I have to admit, he's had no problems and very good performance. I'm thinking seriously of trying it on my '84.

i got offered once from a shop to trade the evacuation of my system of R12 for converting it to R134a and recharging it. stuff is valuable, at least in the hot states.
kind of a shame that all my R12 (what was left of it after 20 years) blew away when i pulled my engine in 05.

I bought the recovery equipment through craigslist for $125. A great deal but I sort of understand why it sold so cheap. I've used it exactly once, it takes up a lot of space and is too big to ship/sell on ebay. I then had to buy a stash tank, freon, and a vacumm pump to do everything. So maybe the buy-in price wasn't all that good. This seems to be kind of a theme with all my Porsche projects. OTOH, this almost guarantees no more AC problems....;]

Most of what I read indicates that cooling capacity will be down if using R-134, mostly due to the small, 'old fashioned' condensers on these cars. When I lived in south Florida the system (with R-12) was adequate but not great. If I'm going to bother doing this rehab I want it to be as good as original. I know some here have said R-134 works fine. I'm giving R-12 one more try. If I still run into problems I'll have to convert to the cheaper stuff...

I've owned a 944 in CA, and now I drive a 944 in Brisbane, Australia (which is a hotter climate than just about anywhere in the US except perhaps Hawaii). Both cars with R134a. I agree with you that the 944 a/c does the job -- it's not as good as, say, my Honda Accord, but it's adequate.
If R-134a can keep my black 944 S2 cool in the middle of a Brisbane summer, I'm sure it can handle temps in CT.
FWIW...

I have spent some time in Brisbane in January... Climate reminded me very mush of south Florida. I thought Brisbane was great. I wouldn't mind living there at all...

Always good to catch up with another Rennlister in person.
