This seems like overkill. http://www.amazon.com/Orbit-91213-One-Dial-Garden-Digital/dp... works phenomenally for 99% percent of cases IMO.
None of the 6 or 7 watering zones I have are attached to a hose. It is all underground with valves and what not. That you linked to isn't really going to work with most underground sprinkler systems... which I am going to suspect account for more than 1% of the cases. I've used those types on one off watering zones and they do work. But I don't think that covers 99% of the watering people do.
