Found the popular edifier s350db for $399 on Kogan / Wireless1 -> becomes $300 after the klarna deal. Delivery free for me.
Also found the Synology ds920+ for $764 delivered for me, a little bit more expensive than the recent eBay deal, good for anyone that missed out and willing paying to pay a bit more ($17).
Hope this helps someone.
Coming up as $845 + delivery for the 920+ for me
