Just curious, what does everyone do with all those good used timers (out of warranty) that you take out of houses when you add zones and need to upgrade them? I have milk crates full of them and am wondering why I bother keeping them. A couple of times a year I might give one to a customer that cant really afford a new one but other than that I dont really know what to do with them. I also have a bunch of old mechanical timers with the pins that I think I save for parts, but I have not taken parts from them since I started collecting them. What do you do with them?
