Full model number:
Panasonic KX-TG6422ES DECT Twin Digital Cordless Phone Set with Answer Machine in Silver, exactly as per the photo
In-store only - I picked up a set on Saturday in Greenhithe (Kent) and there were a couple left.
They are a Which Best Buy and highly rated on amazon too where they are £68 delivered.
Bargain at this price, I'm well pleased with them :o)
