Is this the cheapest place for the TH42PWD7 ? http://www.webelectricals.co.uk/cgi...11bef18c2740ac100158067d+EN/products/1051&2D2 I want the screen in black which is why I'm going for the PWD7 rather than the PW7. Is the look of the unit the same right through the range from the PW6 to the PW7, is it only features that have changed. I take it the PWD7 does have a full functional remote, same as the PW7? Thanks.
