Thanks for your replies Taffy and Lou, I'll await some info from Jon.
My reason for wanting a new digi box is because if we do exchange contracts in the next week or so I'm going to sell our big tele and we'll be stuck with our one from the spare room, which isn't digital, and our old freeview box is knackered. The thought of spending every evening until we fly out watching the standard channels (yes I admit it I have no life

well no baby sitters anyway) fills me with dread.
The stress is starting to get to me, it seems that every night there's another property programme on the tele designed to terrify first time buyers, which convinces me that ours are going to do a runner. The sooner we exchange the better. If we lose this buyer we're going to have to consider coming to NZ without selling the house, which is do-able but not ideal.
The sun is still shining here so I'm going to go and play outside with the kids, that will definitely take my mind of everything.
