Meter Man,
Actually no, there is more to the original ZW Transformers than just power, you must look at the ZW with 4 running Channels with 2 outside Control Handles and 2 inside control handles verses the KW with only 2 train running Handles and Channels and it's non changeable locked in accessory out puts. This means with each individual ZW you get 4 adjustable voltage train running Channels, that can also be used for accessories.
The ZW-L is nice but you can purchase 4 original type 250 or 275 ZW Transformers for even less cost than one ZW-L. IMO you would be much better off monetarily, purchasing 2 completely restored and upgraded 275 ZW's from Jim Lawson right here on the OGR Forum, he restores them better than brand spanking new.
