We had our Guardian meeting the same day as we made our flooring choices, and after blowing our budget there, we were even more conservative than we expected with Guardian. It was pretty clear that from the start, we weren't going to pick a lot. Luckily, our sales rep was not very pushy and understood where we were coming from.
We elected for the wall mount in the family room for our flat screen TV, and a couple of additional cable outlets, but the total was less than $600. We've heard that some folks have spent thousands of dollars on surround sound systems and security systems, but we decided to pass for now. We may do some of that later, but we're content with what we have.
