I've noticed there are some that will do R134 and R12, but they seem to be two units placed together - separate hoses, tanks, etc.

I was told by a couple of shops that the reason they didn't want to fool
with R12 in any way was because they had only one recovery unit and
didn't want to contaminate it with two different refrigerants and
associated other fluids. Kinds made sense at the time - but then I don't
know that much about the issue.

And it's just as illegal to intentionally vent that gas into the atmosphere as it is to vent pressurized gas into the atmosphere. But oddly enough it's not illegal to top off a known leaky system even though you are indirectly doing the same thing!
