Xeon:TalynOne: Yeah, she might bite the cost and get the RT-N66U. It's a crime how much more computer parts cost in NZ, in the US i can get that model for $125 (with free 2 day shipping via my Amazon prime account):

You can always order it off Amazon, $123 + $18 Shipping to NZ (will take a couple of weeks to get here though, and depending on the router might need a power adapter).
I did this and went for a refurb for $80USD.
