Andrews Communications in Sydney do sell the Skywatcher dobs (all of them, and they seem to be in stock) but they may not have a display model setup in their small shop. I believe that they can get one from the warehouse to show prospective customers if they are given a day's notice. Talk to Luke at Andrews.

Go to the Skywatcher page and scroll down to the dob section.
