I have 2 boxes, 50mb broadband, the whole shabang, and i really like it. I only have one + box (the other is the old grey standard one) and it's great. I am sure the next ones will be better (more storage, better response) but at the moment i think their great.
I have the XL packcage and am due to ring them, tell them i'm leaving, and getting some off the bill (they have a tendancy to take the piss if you don't keep them on their toes).
Good luck
