For those who have contemplating buying a TiVo or who are keen on another - my brother-in-law was in Noel Leeming and saw they were down to $199 again.
They're on special until tomorrow - http://www.noelleeming.co.nz/shop/tvs-dvds/freeview-decoders/telecom-tivo/prod114394.html
Having bought one a couple of weeks ago for $250 I'm a bit miffed, but I knew it would happen at some point...
