Knock Sensor advice needed.
 

I'm thinking of getting a knocksensor for my Eunos Roadster, so I can safely fine-tune it myself on the road.
Two systems I'm looking at are the TurboXS Knocklite, and the J&S Ultra Safeguard.

I like the active function of the J&S, but the Knocklite seems simpler (less to go wrong).

Anyone care to share their experiences of these products?

I'd like dammitbeavis to chime in on this thread. He's got the J&S installed in his car. FWIW, I've got the knocksense installed and I'm not happy with the results (it tends to give a false alarm no matter how much I tweak the sensibility).
