When it comes down to it, all the hoses, junctions, clamps, and even the nozzle's are the same. Well nozzle's for the most part. So what you are really buying in a kit is the pump, and that's the most important part. So if I was you, and I'm not, I would find the pump that meets all your needs, flow rate,nozzle capacity (for expansion), and the ability to run dry, are all important features. They are features you have to decide for your self.
For me ecologic and cloudtops.com has the best pumps that fit my needs, but currently I still use a garden sprayer. Some day when I have a true need I will step up to a rainmaker system from ecologic.
Best of luck
