They run, look and sound nice. I don't recall hearing any common electronics issues. Many mechanical parts are shared with older 773s. Personally, I would have preferred if they would have done the silver "773" and Lionel Lines on the tender rather than the rare 60s NYC lettering applied to the 50s tender. None of the Century items has held value. My opinion, trends have changed away from the traditional Lionel Pulmor equipped product making these less desirable. Couple that with more Century product coming available in the market due to people selling because of "lack" of features, downsizing and even death. They are 20 years old (hard to believe) but are still a solid, quality piece.
