What is the best power cable under $200.00 retail?

Used Shunyata Research Diamondbacks are within your price range and an excellent value. I'm not familiar with your exact electronics, so I'm not sure if it will be a good match. There are many other good power cords available used in your price range, from the likes of Virtual Dynamics, and so forth, but to be sure there is a synergy with your equipment you will need to audition them in your system first, which is sometimes difficult to do when purchasing used.
