LostBoyNZ: I work at Dick Smith and can confirm that the Kindle Paperwhite Wi-Fi is completely ad free. It's not the sponsored version. $199 is pretty great, it's $187.46 direct from Amazon (just checked myself), and Amazon expect to ship in "2 to 3 weeks".
I agree, and if you buy it for the business it is cheaper, because you can claim back the GST. Not sure how DSE can sell them so cheaply. Would be good if amazon offered a better deal, such as free shipping.
