Isn't it funny how something seem to get a bad reputation and everyone says to stay away from it. I have had my ZW-c using four 180 watt bricks and the add on meter display for 20 years now still love it. I guess I am just one of the lucky ones.
Another example:
Everyone is has been saying to stay away from earlier PS 2 MTH engines due to failures but I have had to have more PS3 locos repaired than I ever did PS2!
Good luck on your decision,
Don
