Im considering buying a Panny 6 from AV sales. I just thought I would check with Richer Sounds before I buy. richer sounds are offering the same deal for £1649 and av sales are doing £1580. The only difference is richer sounds offer a 1 year at home warranty. Is it worth to pay the extra money fro the warranty from richer sounds or do all panny 6 screens come with this warranty?
