mjmch2003,
I too like the flexibility of interchanging power cords, but I look at the CPT Equi=Core 50/150/300 AS a power cord, only with a network (the balanced power unit) built into it, also with the option of adding an outlet strip to feed more components (subject to the total power draw rating of the particular CPT model).
I think Mark @ CPT offers upgraded power cord options on some models, so you could inquire about that option if it is of interest to you.
