Irrigation systems are definitely worth it!! I just re-vamped our system without any previous knowledge and it's working great. I recommend Sprinkler Warehouse and Berry Hill because they both have great online and phone help for building a system. I recommend looking into some kits online and seeing the pieces that you need and then putting it together on your own. Generally, the main components you need are a a timer, spaghetti tubing, and stakes. If it's required, a pressure regulator and tube couplings may be needed. I just looked at the kits and they're pretty cheap and a good starter for a home garden.
