A good price that hasn't been this low since June according to Camelx3
Price is back down to $84.99USD again (from $94.99USD) plus shipping $13.97USD shipping to NZ.
Note it seems the Roku comes with a 110v power supply so you will need to purchase an adapter for use in NZ. However, some people have reported that it can run on 220v with an adapter plug.
Roku Set Up Guide
DNS services: Getflix UnBlockUS.
What do you need:
A Roku box bought from the US. This is an important point as Roku has different firmware installed on each country’s device. So, if you bought one in the UK, that will not work for US channels and vice versa.
A compatible DNS service. It is important that your DNS service not only works with the Channels used by the Roku box, but also works during the set-up stage – not all do! This guide has been tested with Overplay’s SmartDNS service which works at both stages.
A Router which you can configure the DNS settings. Normally this can be done on the device itself, but the Roku box is one of the few streaming platforms that do not allow any network configurations.
