I got an estimate yesterday from H-Town Seamless Gutters, Horacio. Really nice guy and recommended by several others on TexAgs. He said he would install the gutters for $300. He even had more color choices than the other guys. Keep in mind it's only the front of my house, but considering the others gave estimates of over $400, I am using H-Town.
