On the other extreme, a simple drip system is a $50 starter kit from HD, $50 of additional emitters and tubing, and a $40 battery powered timer that screws to your hose bib and controls two drip circuits. I put one in this spring, waters all the plants in our backyard and some of the front yard planters, saves me a few hours a week in the summer.

If all you want to do is water three 3' x 10' beds, I'd consider a simple drip system. You can use soaker hose instead of individual emitters. I've never tried the micro sprayers and micro sprinklers.
