First poster, but big fan of OzBargain.
Have been keeping an eye out on this one and missed out on the DJ Black Friday sale at $263.20 (https://www.ozbargain.com.au/node/654677).
Noting the disclaimer from Build and Play that it is for builders and not collectors, but this is referring to the fact they cannot guarantee the condition of the box (i.e. potentially minor scratches).
13/12 update: Shipping no longer included / Free shipping to Melbourne Metro only
I love it… but could probably buy a real typewriter for less
