I'm about to buy a new telly and I think I'm going to plump for the JVC AV28X4, which is £529.00 from John Lewis but hopefully I can get them to pricematch down to Comet's £399.99. (Online retailers sell it for as little as £353 delivered.) But... The model that Comet is selling is the AV28X47, and the only review I've seen is actually of the AV28X4SKA (which Kelkoo doesn't seem to have heard of). Does anyone here know the differences (if any) between these three models? Any other advice relating to this set? Oh, and also a complete newbie question: do you need special RGB scart cables to take full advantage of the RGB sockets?
