NOS but i would swap out the noids for NX. ive heard plenty of people have problems with thiers and i have personally had problems. both NOS and NX have, to me, the same quality tech lines as well.

Most solenoids are made by the same companies. They are just repackaged propane valves. No one kit is better then the other. Some may draw more amps then others but that is about it. And everyones jetting is based on their bottle pressures. Usually between 900-1050 psi. Prices will depend on how complete teh kit is. I call that laziness because you are paying a premium for little AN fittings and AN lines that you could buy sperartely and they usually don't fit after you want your solenoids mounted in a different place anyways.
