I think Pantera Performance was in the same ballpark for the units, but then you add about $100 or so for the cable (With IPS, it sounds like they recommend vendors for the cable rather than carry it themselves). Ultimately, they'd both come out around $700.
Precision Performance carries the stock replacement cable for $159.00.
I guess it boils down to how much benefit there is to the very cool looking, and I assume better gripping, brake from IPS, or just replacing the cable and using the $500 I save on gas, or racing belts, or a new steering wheel, or ...
Since I've only had the car for a short while, I'm not sure with whether the stock parking brake design is worth the investment in a new cable, or if it will work for all of a week after being adjusted before it needs to be adjusted again.
