Have paid £13 for a cable like this, more than once. Seems to work just as well. If only I'd known sooner! Using it to connect my laptop to my Home Plug network - the solution to all the connection problems I had with my wireless Sky broadband. Also good for connecting Sky+HD box to Sky broadband via Home Plug for Sky Anytime + (brilliant!).
Very good book if you like to know about the behaviour of your garden birds. Has all the usual information to help with identification plus information on what aspects of each bird's behaviour make it special. Keep it by your window!
