afcnz: As for me, as far as I know (/was told) this is one of, if not the only, units that will work (or work well) in my region...
That's not true. Vu+ receivers will work anywhere in NZ so long as you have a Sky dish (or FreeView dish) installed:
I have been running a Vu+ for almost a year now, and it does everything you could realistically want. Prices on that site are in AU$, but they are a good company to deal with, and stand behind their product with warranty service and spare parts in stock.
Cost is a bit more than the Dish TV units, but you get what you pay for!
