Lanscapers and garden mavens: Need a bulletproof irrigation valve

My dad’s good and sick of replacing irrigation solenoid valves, and he wants to know the best to get, cost be hanged. Is there a clear winner?

I’ve had good success with Champion Irrigation brass valves. They are not cheap but last a long time. I’ve had to replace the diaphragm in a couple. They are 14 years old now and are doing well.
