I seem to remember there was one of these on Trade Me a couple of years ago relisted several times. I don't think it ever reached reserve price so I'm not sure what happened to it.
It was being sold be someone I Dunedin from memory. It might even be a member of this forum?
The ESC key is bust, so I'll need to figure out how to fix this. I also have no idea if it actually works, as I will need to build a power supply first.
