You really should consider an IR repeater system rather than the RS pyramids. I have used the pyramids for around 3 years, and I am now in the process of installing an IR repeating system as part of an overall remodeling of our house. The pyramids have served me well, overall, but they fail to transmit the commands maybe 5% of the time. While that doesn't seem so bad, it does get on your nerves after a while. The placement of the pyramids greatly affects their performance (due to interference from the electrical system, sunlight, etc.), so certain locations may now work well at all. I have also had two of them fail, and had to replace them. The IR repeater system is slightly more expensive, but it is worth it.

The only major problem with IR repeaters is that the wiring can be difficult. But, if you are pulling wires anyway, then that is not an issue.
