Peco point motors are fine, you will need an auxiliary switch with it if you are powering the frog on the point, as you need to switch the polarity on the frog as the point switches.You don't have to power the frog, but you are relying on the side of the frog and rail for electrical continuity. If you need a second switch for an LED to show which way the point is set you will need a PL-15 twin micro switch. These are a pain as you have to assemble them, it took me 2 hours the other day to assemble 18 of them! The Seep point motor has all this built in and works out cheaper.
