Hi! I just ordered a factory refurbished Nikon S8100 from Cameta Camera. They were recommended to me by several photographers. There is a 30 day return policy and one year warranty. You can double the warranty by using an American Express card. I bought mine in an ebay auction, but they have a lot of them on their website too. They are a authorized Nikon dealer and they appear to get a lot of factory demo cameras. They come from Nikon sealed.
It's worth considering.
