I know people lover Eric's trains and more power to them. However, his reviews just grind on me. I have watched some of this other stuff as well, I just don't dig it.
The only regular Model RR Guy I watch is Luke Towan, he seems to always be doing something different and new. There are other non Model RR things I frequent on YouTube, but alas my interests are pretty varied, so my watching reflects that. Trains are not my only hobby or interest.
