Bought a camera in Hawaii when I was over there in may, as my camera broke. Wasn't anything super flash, but price was not really better than Aus.
It's more expensive to buy in Hawaii than in mainland USA, but I think they probably mark up cameras a little higher, as the is no shortage of awesome places to photograph.
My favorite of the trip. Taken on a crappy 8 megapixel, 3x zoom camera from walmart.
