I purchased them all new. And after time, new versions were released that improved the switch. I did buy the latest versions and replaced the older ones. The ones today are virtually flawless. And I buy them Ross-Ready with DZ-2500C machines and pre-wired (outer and inner rails soldered). If you desire non-detailing you will need to wire the trigger rails back to the DZ-2500Cs green and yellow wires.
Note these are well made but not made "metal" like the 022 they are instead made to look like scale turnouts with wood ties as a result you can't bang them up like the 022s; or walk on them!!
My suggestion is to buy a few and see how you like them.
Thanks, Alan. Fortunately (depending on how you look at it), my layout headroom is so low that people can't really walk on the layout so stuff doesn't take much of a beating. My son's layout in his room, however, gets a daily trampling - no turnouts there!
Looking at the Ross site, it appears that if you buy them with the motors, they also come with a switch controller. I am examining my layout closely to see what style I will use. The fact that he offers the wye, the four way, and the curved switches provides a lot of flexibility, which is important to me because I am doing this freehand.
