Wanted some opinions from the forum. How close or far away from each other are the Vista, Clarity and Source. From what I have seen the Clarity and Source are about the same price on the used market and the Vistas are about double the used price of the Clarity and Source new. Is the double price worth it or is the Clarity and Source a better buy. And as far as the Clarity and Source go how close are they to each other in performance?
