|Mmm - agree it's hard to find...|
eBay/Amazon both have simple adapters listed... Bearing in mind comments in the link I posted earlier, I can't see any great risk in trying one of the listed adapters, as they are generally quite inexpensive?
I would incline to one that isn't rock bottom price, and possibly try a simple connector style adapter initially - rather than a cable style? Although the cable style may be equally ok - or not (applicable of course to both style...).
