wheresa good place online to buy one or two of these cheap?

Mainly I want one to turn on a house light or additional garage light when i come home
thanks

 

not sure about online but you could check Home Depot. I always wanted to get one but never did. I love the fact that i dont need a transmitter for my garage door. My old 98 CL had this feature too so ive been spoiled for the past 3 years!

 

Home depot carries X10 products. You can also get them online at www.X10.com.
