I have never had the urge to model HO, my dad still models in HO and I have helped him on his layout. I also just finished detailing an HO locomotive for a UP engineer. What a pain! I superdetail N Scale engines all the time, because of my pickiness, the HO engines become a nightmare. The rivets are big enough to count! To each their own, I like mine in N. I've been with the scale since I was 8 and 28 years later I have no desire to change.
