I bought mine when I only had the 400mm f/5.6L and it improved the quality of those shots as compared to using a pretty good Manfrotto and the Manfrotto gimbal.
Finding a good used 500mm f/4 is hard to find. I couldn't find one and the pricing that I did see seemed to offer too little discount over the new price. Still, if you can find one, you should be well protected from cost devaluation.
