I have bought the cheaper consumer version of the MX series called the Unifier100. Cost CDN$110, controls up to eight devices. Since I have an electric fireplace with remote in my theatre- I programmed this into the remote and can now adjust the heat and flame.
Even has macros so I have set up a couple for the wife when she wants to watch TV or a DVD. Shuts everything on automatically.
Easy to understand, works great, and just over 100 bucks!
