These are almost new projectors that might have just been returned without being open but the box isn't perfect, or just used for a fraction of the hours as a demo unit. They offer exceptional value and save you loads. If there are non listed it is still worth calling us with a spec and we can find you a model that will work.
There is a considerable amount to be saved for buying a slightly tatty box, it does not effect the warranty or one with minimal hours.
