Home Theatre Concepts helped me select full home theater components. I put a lot of it together on my own and they talked through the entire plan giving me good ideas, suggestions, and pointing me in good directions. A good part of the experience is that they don't try to steer you to expensive products. They let you know your options, the pros and cons, and try to help you with your decisions.
Overall, they're really friendly guys and it was a really good experience.
