I take it you only have to order before November rather than have it installed? They can't fit me in until 22nd of Nov, but gonna order a second box this weekend.
On a related note; I had a repair to a V+ box booked in for today because I had to wait until Nov 22nd for Tivo, but when the engineer got to my house and started work I was chatting to him about Tivo and he said he had a spare unit in his van so he could install it for me today. Jolly nice of him and now I have Tivo four weeks earlier than I thought I would.
