Redsy,
I have been installing home automation since 1996. X-10 is cheap and works okay, but it has a slow response to commands. The advantage to X-10 is you can retrofit any home with it just by changing switches. I prefer SwitchLinc products over Leviton and X-10 brands. SwitchLinc and Leviton products can be purchased from
