I'd try all the Apple dealers in your area for a used one. Up here in Toronto there are lots around near your price point. Also you might find a non-Apple dealer that specializes in used Apple stuff. All Apple dealers have access to special deals on refurbs as well and usually the guarantee applies. I believe you are much better off staying with OEM equipment. Everything works the way it's supposed to and you'll feel much better sitting behind that logo. Chances are you will be able to trade in your present one to help on the deal.
