Tempting but still way more expensive than purchasing from Google Play.
I just saw another site
Selling the N4 8gb only for $615 including GST and shipping. It appears that they import them and have them available now. (not confirmed)
This option is cheaper than Mobicity.co.nz as from previous experience you will still need to pay duty once ordered
But this is still $215 more than you would pay online at Google. So it all depends on how much you want one and how much you enjoy the VPNing int shipping etc.
I for one will hang on till available again ....but then I am not in a great rush. Come on Google, release my Christmas present :-)
