I have two zw-c with all 180 bricks and on the accessory/iner handels they each have 135 watt bricks. If you know how to fix the issues with these they can be a nice transformer. I know its overkill but I run command all the time and just like the looks and the ability to turn the sections of the railroad on buy turning up the handels. If you look around they can be had for a decent price. The zw-l is much better, but cost a lot more. I paid less for my two zw-c's used than the cost of a new zw-l.
They just needed the main chip upgraded and the metal brackets installed. Lionel will have the upgraded chips just call customer service and ask for them. They also have the metal brackets for the handels. At least they had then when I ordered mine. It was easy to do and now they operate fine. Mike regan did a video on these wich is very helpfull for the chip fix and explains the powemaster operations well. I recommend to anyone to watch it on youtube. I am happy with mine.
