Is there anyone running TPMS in their s13 or s14?

[sac]

hey guys.
With my current dd it has the tpms. TPMS is a abreviated term for
Tire Pressure Monitoring System for those that did not know.
yesterday my light on dash came on. So i inspected my tires and found a dam nail. kinda sucks that i picked up a nail, but the system told me their was a problem, so i could plug the tire, take it in have it dismounted,patched,and put back on the rim. Could have saved me the cost of a new tire. (well 4. its a evo!) I was pretty impressed about the whole thing.

i know there are downfalls to the system. I know there are aftermarket kits i could buy that would let me put this in my s14. But is anyone running the system?
