Which is why I've taken a punt on it. To get a working HD20 sent down to Australia, typically from the USA, costs a mint. The little buggers can be expensive enough, but when the exorbitant courier costs are added on it is typically out of the question.
Like I said, if I can get it to work/connect, I win, if not, it becomes an interesting drive enclosure, and it still will work fine to lift my 512k up a couple of inches to a more comfortable viewing/operating height.
