My team always gets the CKD solenoids from AndyMark, and we haven't had any issues. Remember to get 3 M5 Pisco fittings (sold from AndyMark too) and tighten these using an allen key inside (it's tapeless but you need to tighten it from inside the fitting.) I recommend a single-acting solenoid for this use, so it will return automatically to a certain direction if your robot loses a signal or the wire tears loose for some reason. Hope it helps!
