If it's the same 'old shit' (sorry for the bad language), as all the bad 'internet conversion collections' for other brands
that has been floating at eBay and elsewhere for years, it's probably not worth it.
Of course you can be lucky to find a file or two that is reasonable OK, but mostly it's just 'raw conversions' between
different brands / older models legacy styles.
Imagine tweak more than 9000 styles for all the brands to make it sound good??
