I spoke to Stewart at Boss Components (makers of Magnefine). Apparently their patents lapsed recently so the market is being flooded by clones. While he did not make any claims about the Raybestos filter directly, many of the clones offer virtually no filtration benefit and some do break or leak.
I went with the ebay version because the supplier seemed reputable and I believed I would indeed get a Magnefine filter given the ad mentioned the brand name 5 times (not to mention OEM supplier, patented design etc). Needless to say, the Chinese made Raybestos filter is not patented nor used by OEM so I'm arguing that point with the ebay seller at the moment.
Anyway, if you're after a genuine Magnefine filter that is made in Australia to ISO quality standards, Repco can source them. It's stock number 71200 and it costs $38. I've spent $140 changing the oil so I don't personally see the benefit in saving $20 on a filter that may fail with expensive consequences.
