Yes, if buying a dell keep an eye on the dell factory outlet (DFO) for refurb and as-new stock (Dell Factory Outlet). Ordering process is a bit clunky: call or internet chat with them, they go away and see if the item is still available, couple of hours-days (if on weekends) later they get back to you.
Eyes on Rathdowne (Rathdowne St, Carlton, Melbourne) has provided me with great service. There's a couple of comments about them in this thread. I've been meaning to go back to get some prescription lenses put into my sunglass frames.
