Idk about your price range but I have used Key Digital and Shinybow without issues. There are also new IP scalable systems where you do not need at fixed matrix that most companies have such as Just Add Power, Shinybow, and Liberty AV. You just buy Receivers for your TVs and Transmitters for your sources.
