just my two cents worth

Yeah, what he said
I went out to check the fluids cabinet, and to my surprise, I found what I used "back in the day" -- It's called Ester 100, and says on the back of the bottle it's to be used in R-12 and r-134 systems. I don't see the harm in doing the work yourself, but at the same time, it's kind of a crap-shoot. It will either work and you'll be happy, or you'll have a leak, and it won't last that long... then you'll probably want to have it vacuumed and leak-tested at a shop.
I think I paid about 35 bucks for a quart some time ago, but it looks like the price came down a bit, or I got robbed:
