If you don't mind getting under your layout the Tortoise switch machines are the best way to go. When viewed from above the only thing you see is a fine wire engaging the switch throw bar. They are easy to wire, and after you do one installation, the next several will take about 20-30 minutes each. I have used them on my layout since 1987. They are American made in Illinois. They are bullet proof. No crappy linkage. You will never derail with the Tortoise unless you throw the switch the wrong way. No more ugly Atlas switch machines.
