I should think he is very proud of this accomplishment!
That really wasn't that big of an achievement, the reason that MTH was able to get a UL certification, is because while the Z-4000 may have a TOTAL output of 400 watts, it is limited to 180 maximum through any single channel.
The new Lionel ZW-L is refered to as a 720 watt transformer, and will deliver up to 180 watts to each of the four channels, per Lionels on-line manual, it will not deliver more than 180 watts to any single channel, AND will not exceed a cumulative output across the four channels exceding 620 watts total. whichever channel would exceed the 620 limit will be restricted in output to the 620 watt total maximum, until another channels output is reduced, and can be applied to the restricted channel, again up to a 620 watt maximum total output.
So for SELF-CONTAINED output (IE, no external bricks) the ZW-L is the far away winner, as to having a UL listing, I don't know if it has one or not, I could not find that information.
For Mike Wolf it has to be the satisfaction of starting his own business in his parent's garage and growing it into what it has become today. The old "American Dream".

To ME, I think Dennis is right, what Mike has achieved with his company probably way over shadows, the success
of a single item such as the Z-4000, which many people are very Happy with, and I am not saying, is not a Good product.
