I like the 'leaky' hoses, as I call them. Here is a link which shows the basics for a soaker hose set-up. Only run the hoses where the water is needed and keep it just under the surface of the mulch. Rather than hook up to the water spigot with all the expensive components, I attach the leader hose (non-leaky) to the rain barrel which is elevated so the water uses gravity and the amount of water is only what's in the barrel or whenever I turn off the tap. If there is no rain, I pre-fill the barrel using the garden hose. No more dragging hoses all over the yard.
