I personally, from a contractors standpoint, wouldn't trust anything from the home improvement stores, so I am not sure how reliable their products are. If you do go that route, make sure it has a decent warranty. I work with a manufacturer by the name of Olson Irrigation, and they make an excellent pre-made valve box with a wire terminal, shut off valve and everything already built into the box. It is a little bit more pricey, but well worth it in my opinion. You can check it out at http://www.olsonirrigation.com/PROD/OISproin.html
