How much scalability do you need?
In part, the answer here relates to the previous question about your overall interests.  Some systems are designed for basic tasks and not much else. Other systems are capable of sending not just control commands, but also data-intensive media like video and audio throughout the house.  You want the flexibility to be able to build on today’s purchases tomorrow. Brands and technical platforms aren’t necessarily compatible with each other, so it pays to consider the future when you begin to assemble the system. 

The Control4 HD-250 ($599) is a good starter controller for a home theater or media room but can be expanded to meet a home’s growing needs.
