I am seriously considering getting Sky HD (I am currently not a Sky subscriber) and am undecided on what room to put it in. One of the rooms on my list does not have a phone line installed. Does anyone have a knowledge of the wireless phone senders such as this: http://www.amazon.co.uk/RTX-WTA-111-Wireless-Phone/dp/B000NJQHL4/ref=sr_1_1?ie=UTF8&s=electronics&qid=1233837159&sr=8-1 ?. There seems to be a mix of reviews between "yes it all worked fine" and "no it doesnt work at all with HD". Anyone used one of these successfully or unsuccessfully?
