Is this adjustable top strut worth it for my MK1?

Hello,
What is the best adjustable strut top, do I get one with a fixed central hole so as I adjust the camber it also moves the castor or should I get one where the camber is adjusted on a slide?
is the below mount worth $290 Australian dollars delivered? Can I buy better in Australia?
