It's not even a famous DM-2 (ie used by some pop band) or NM in box, but somehow managed around $127 more than the average price I've recorded the last few months ($300-320). There were 5 DM-2s in April, so it's not as if there hadn't been one available for a while. Makes me feel worse that I didn't have a crack on the one that was near min with box that went for $290
I just did a quick eBay search here, and the recently sold DM-2s went for as low as $150US twice recently, and as high as $357US, but seem to average about $200US. I don't know what the conversion rate is for US $ into Australian $, so I am not sure if that is about the same or not....
