Take another interest of mine, radio control. I used to think rc was expensive. RC can fly through the air. There are pre built scale aircraft that come with pretty much everything you need except radio for <$250. A train really only follows the path you've laid for it. Sound is neat, but does that justify? Is rc just cheap technology?
Don't take this the wrong way, I love these trains, I love just looking at the boxes that contain them. They bring me much happiness to take them out and enjoy them and it's likely we will never part. Just wondering where the cost comes from?
