If you set 'em up properly there is nothing wrong with the Post War Z"-Dub. I've been using one for about a year with both DCS and Legacy without a hitch. I also have a MTH Z-4000 for a back-up only because I got a Heck Of A Deal on it. Yeah, I like the digital meters but there will ALWAYS be as place for a "Z"-Dub on just about any layout for one reason or another. Just Sayin'.
