Curt,
No problem getting R12 just what a shop may charge you for it. Could be $90/can.
Ask before you commit.

Does it have the "Do It Yourself" manual transmission, or the superior "Fully Equipped by Porsche" Automatic Transmission?

Stick to R-12, there are plenty of independent shops around that still have it and it has been my experience that 928 systems work much better with it. 134 is no bargain these days anyway. Fix yours and stay with R-12.

My educated guess would be compressor, condenser and expansion valve. Maybe also the evaporator.
A check of part numbers in PET would pin it down.

There is no drop-in replacement.
Re Duracool. Ask yourself if you want a flammable gas in there? Under pressure? Mounted low and up front so as to be one of the first things to take impact in the front end or from bottoming. Most of the cheap so-called replacements are butane or propane derivatives. I would not.

I had a bad hose about 5 years ago, and w/all the hoopla surrounding R12 in CA, I converted to 134. had to change the dryer and some old seals - then refilled w/134 and it's been cold as ice w/my dual AC system in 100F+ socal days w/no problem, even idling in traffic.
did have some contacts get nasty on the low pressure switch last month, but after they were cleaned up life was cool again
