Trust me you are much better off with the DZ1000's. We had installed 50 of them on some of our mainline switches and they caused MAJOR problems. They look good because they are smaller and throw slow but and its a major BUT is the following down sides
1- You can't switch them manually ( There is a button on them to throw them but does not allow a mechanical throw)
2- If one of the motors on the data wire driver has a problem it hangs all of them up Very hard to find the problem motor especially if you have a lot of real estate to cover
3- The ones we had would just decide to throw by themselves especially when connected on a crossover Caused numerous head ons
We have over 300 DZ1000's and they are easier and way more reliable
