i have a jbj CO2 gauge/solenoid/needle valve combo. bought them from florida dritwood. first one was faulty, solenoid did not cut off CO2 flow when off. second one works ok, but the needle valve does not have very precise control, hard to set the bubble count you want. and for some reason when i change CO2 tanks for refill, i have to re-adjust that needle valve.
never had another set up, so i dont have anything to compare it to, but i think you could do better, esp with the needle valve.
