I ordered this last week from a different company and paid slightly more! And being my bargain hunting self I couldnt resist checking to see if the price had come down and I found this. I havent actually installed mine yet but I checked it out in Currys before I ordered and quality looks good and also has decent reviews online! Plus i think it looks good.
And next cheapest I can find is Currys £464.99 (with voucher)
