Actually, I've found some things are cheaper
at Radio Shack. Like the universal module,
and sometimes the wall switch modules. If
you are making a small purchase, it also
allows you to avoid shipping, plus you can
get it that same day, 'cause you go get it
yourself.
I was just in Radio Shack yesterday. They
have a new design on their lamp and
appliance modules. They now have a door on
the front to cover the rotary switches. It
gives them a cleaner, less industrial look.
