This is more than the unit I found at DSE, but which was unavailable in my area. It's cheaper than the unit I ended up buying at Coles ($60) - but only just once you factor postage. I don't know how units differ, but Deals Direct also has an alternate unit at the same price. Check the specs if you're interested.
