I believe the new RRP on these is £179.99. The cheapest new ones I have found, (having done a quick search) is £116 from a seller on Amazon, (only 2 left), including postage and the prices seem to go up from there. It's a fairly pricey £161.99 at Argos.
I have bought refurbished products from the Panasonic outlet on ebay before and never had a problem, with the items looking new and only the packaging showing wear.
You also get the peace of mind knowing that it's the manufacturer that has refurbished the product and you also get a 12 month warranty. All in all, it seems like a very good deal to me.
