I am looking to add some Alco RS units to run alongside the rival GP7 and GP9s; however, since MTH doesn't have a premier RS 1, 3, or 5 engine cataloged, I am at a loss as to which of the other O scale makers might have produced a high-quality model with the same level of detail as MTH premier.
Would love the thoughts and guidance from this group on what to look for and perhaps what to watch out for.
Thank you
