Well, what CAN you get up there? Lucas, Motul, Castrol, Prestone (my favorite) - They're all good and should be readily available. Stay away from "Finish Line" as it is based on mineral oil 
The Haynes VW manual says either DOT 3 or DOT 4 (which can be mixed in-circuit, successfully). Stay away from DOT 5 fluids ("Run, Forest!") as it is for racing and absorbs water more than the lower numbers.
DOT 4 can tolerate higher fluid temps, so if you're tracking your buzz-bomb, that's the stuff for you. If not, DOT 3 is fine.
Haynes also doesn't care who made it (or what color the fluid is). We used to be able to get either lite amber or blue fluid, but the DOT didn't like the blue, for some reason, so it is NLA. Was nice to alternate the colors when bleeding year-to-year - made it easy to know when the new stuff made it to the wheel as it changed color of the flow.
