I'm after one of those thingies, you know, extension cables with 4, 6 or 8 sockets that plug into one main socket and protect against surge etc. I have tried doing searches, but as I don't know what they are actually called its proving difficult! I remember reading a review in one of the mags but I can't find it. Budget around £40-50 max. I need at least a 2m cable, preferably 3m. Any suggestions? Thanks in advance.
