I have a Netgear DGND3700v2, a rock solid ADSL router with dual band 300mbit wireless (802.11a/b/g/n) here that is no-longer needed. Many can vouch it's an awesome router with plenty of features such as guest network support, IPv6, gigabit wired, WAN port and a very good ADSL2+ modem.
These retail for this on the internet is $199, I personally paid $249 for it just 6 months ago, you can have it for $125 + shipping (or pickup in Wellington CBD)
I personally currently have it hooked up to a Telecom VDSL router (running in bridge mode) and it's wireless performance and coverage is awesome, if you're looking for a fast router look no further, this has plenty of grunt for even 100mbit UFB.
If you're running a modem supplied by your ISP light it on fire* right now and purchase this, you won't regret it.
*I accept no responsibility if you decide to breathe in the smoke of this causing cancer in the process, please don't really do this.
