We are re-doing a lot of switches, plugs, plates, etc. All rocker switches. It has been stages with some stages still to come but we are at about 15 - 20 dimmer switches (Lutron dimmer for LED), 20-30 standard rocker swithces (both single pole and 3 way), 20+ new plugs and 30+ new cover plates.
The Lutron dimmer were obviously most expense and I actually found a really good deal on Amazon for them. I was suprised. Beat everything i saw online by several dollars per.
For the "standard" rockers, I went with Levitron Decor and at about $2/ I did not bother pricing around much. I just bought from Home Depot out of convenicence.
After failing miserable on a three-way switch, I admited defeat and have hired an electrician to come out each time. They only charge about $75 per hour and really knock out a lot. I was satisfied plus provides piece of mind knowing I didnt do something stupid
