I have a Morphy Richards 5ish inch Colour TV/Radio alarm, and I thought of you. Yes, colour! And it's 240v/12v with socket for aerial and a socket for 12v (ie it hasnae got an aerial or a 12v adapter). It seems to work quite well with just a set of keys as a TV aerial. FREE (we can't sell things here of course) plus er 50 quid P&P. call me 020 8303 3329 work.
