I have one and love it. It is one of the few non-scale locos I run, big enough that it mixes with most scale steamers and diesels and can visual pass for "big enough," and it looks like a Big Boy, yet looks good on curves, something no scale Big Boy ever has for me (too much boiler front stick out for me).
I had a previous LM Big Boy and literall wore it out. I treasure this one.
It is detailed and worth the money. Mine runs perfectly and pulls a lot. I prefer to run it with an LC+2.0 universal remote.
