Is there any reason not to get them? Would be coming from the US via a reshipper so the absurd NZ markups are a non issue.
DoomlordVekk: Get a couple of the Mikrotik 750G switches, 5xGb ports, full 802.1q trunking. No more than about $180NZ from goWifi or even trademe.
GoWifi will also have bigger Mikrotik switches, most likely.
