i am doing a major remodeling on my house. I want to install a home theater in my basement and wire the entire house for sound and networking. I have met with two separate installers to design the systems. i have been recomended very high end systems that seem great. my issue/concern is that when i do a little bit of research on the hardware costs (projectors/receivers/speakers/screens, etc) the markups are ranging anywhere from 30 - 80%. Is that typical? i thought the benefit of using these types of people was that they could get you better deals and they would charge you for the install. I feel like i am getting it on both ends.
