I have to give my local Htg some props. They make a lot of thier own items like ballast, hoods, and other various things. What I have found is that there is not a lot of shops that fix ballast but Htg not only stands behind thier product but in a lot of cases they fix them for free. I bought a ballast from a friend that needed an ignitor. It was one of thier 1st models. They gladly fixed it and did so for FREE. Personally if you have one locally, go there and spend your money. If you do run into problems they are right down the street to fix them for you. Way better than dealing with mailing stuff out and waiting......
