Hey, thanks for the reply!
I did manage to find just one seller on Amazon that still had them, and a few on ali express, but all very expensive for a single use tool. The days of picking one up for $60 (at least in Aus) are over sadly.
USPS should be able to send it in one of their flat rate medium boxes, just waiting to hear back from the ebay person to see exactly why the other one bounced the first time.
Will PM you about how much you'd be after for it
