Individuals have to decide whether (or not) that extra detailing is worth the (approximately) double price over LC +V2 . BUT- an early 2000s Legacy is a bargain, and should also be considered. In some respects, I think those early ones were better- better crew talk, tailored to the road number, for example. Many of those were made in Korea, which I think are better than the Chinese ones.
The catalog description "can motor w/ flywheel" does not mean identical QUALITY of motor. The set loco's DC motor vs. the motors in LC+ ones I have are night and day.
1. Run a set loco (from a set priced at $250) for HOURS a day or run a lot of cars = early motor failure.
2. I run LC+ and Legacy engines on a medium sized layout and plastic/metal cars. I have had NO motor issues w/ LC+ locos. I am sure the motors used, the running gear, etc. might also be still better again once you go to Legacy.
But ultimately- one has to value his approach to the hobby. If trains are a side interest, then maybe buying $1200 engines is not a good idea. I tend to do everything "whole hog". "Your results might differ."
