Hi Peter:
I went with Atlas turnouts. I haven't had problems. I was able to wire them to both the switch controller that comes with the turnout as well as to the Lionel SC-2 successfully (i do not consider myself an expert). Also, help is always around here on the Forum as well as on the Internet.
I haven't eve rtried Ross turnouts but have heard they are excellent. I liked the fact that the Atlas track all "matches" and was able to order everything from one vendor.
Hope this heps,
Bruce
