Question
I am interested in knowing if you have any recommendations on various company sprinkler heads?  I am leaning towards K2 seems to be more cost effective. Can you advise? Thanks

Answer
I believe that you get what you pay for in irrigation equipment.  I have never used K2 sprinklers, and dont know much about their history.  I looked them over at a store recently, and thought they were fairly well constructed, and seemed to have easy to service features.
