I am using peco solenoids on peco points & tortoise on the hand made points so that they do not suffer the slam-bam of solenoids. They are a bit dearer than Peco but at least they have 2 changeover switches & I find that they are quiet even at the stall mode. I use 9v only & one of my Australian friends uses 6v & he indicates they are quieter again & still work OK.
The point blades have to be free moving though. A couple of years ago, I used Lemaco, work well but are noisy until they switch off - at least you know they are working.
