CHEAP remote “push button” solution?

I was going to go out and see what was available in the “CB” frequency range because products operating in that range tend to be very reliable and inexpensive. Then I looked into the Harmony products… pure genius!!! That’s how I’d do it (and I’ll probably buy some for myself to get familiar with them).
Whenever I least expect it I always learn something new (and usually beneficial) from this website).
