You will find these discussions in just about any hobby. In addition to trains, I also play guitar..some of them are very expensive..some not as much. But, they are all good and usable instruments. With trains, I have a few modern ones but prefer tinkering with pre and postwar. Enjoyment for me is found in keeping these classics running and have even upgraded old transformers. I was a lone wolf but it's fun hanging out here and getting a different perspective on what others are doing or have done.
My advice....do what you want and enjoy what you like. Fendermain
