Yeah, will probably end up going that ebay link unless I can find a single-mass thats got minimal/no chatter and significantly cheaper. Man I hate how the flywheel costs so much on European cars. Would actually be fine if the aud was actually decent, would have been pretty cheap otherwise.
Good thing i'm doing the install myself or I'd have to add another $800 or so in labour.
Found the clutch tool as well:
