Way back when it was a couple of cents per foot for cat 3 and maybe 8 or 10 cents for cat 5 or 5E. There was always a bigger spread for the "newer" cable.

There is zero performance improvement and I was actually told by a chemist once that by the time any PVC in data cable hurts you something else will have already done you in!
