Dennis,
Your shop is right, all E30 iX's had compressors that are non-compatible 
with R134a: http://www.koalamotorsport.com/tech/misc/ac.htm

You could look at the Koala's web site for that info, but I would shop for 
a new compressor instead. It may cost a few extra C-notes, but with all 
the labor cost of performing a R134a retrofit, you would not want to 
chance it on an unknown used compressor.
Plus, new compressors are more efficient and will be putting less straing 
on an already heavy breathing M20 engine.

Sell the car as is.
Put a ton of money into it and keep it.
Is that general enough? ;-)

Also a very good time to replace the expansion valve (if it is original) - 
that's about 3 hours of labor.
Check for any leaks once you put it all together. 15 year old hoses are 
just that.
