The products are exactly the same. I used the Rainbird products (item numbers were the same) from this web site - sprinlerwarehouse.com. There is no labor to figure into his prices since we were dealing with material only. I have found the Rainbird products (controllers, sprinkler heads, etc.) to be about 30% cheaper on this site. The only thing that he had a better price on was the PVC fittings. Both carry the manufactures warranty.
