is a link to the thread of people trying to find stores that still have them...
This is the one, in the top right for $69.
If you haven't tried digital TV, I think it's in all the capital cities... it's free, uses your existing antenna, all you need is the new tuner (in this box) and you get crystal clear tv and extra channels like ABC2 (a second abc with better programs).... Hiiighly recommended.. NZ'ers, let me know if u know of anything similar there, or planned.
