I've really been getting attracted to N gauge trains. I feel a little guilty about it because I've grown up on O27 and I love the big engines. Not to mention, I just bought my daughter an HO for Christmas. Still, it seems like I could do so much more with N gauge using the limited amount of space I have. Would I be considered greedy for wanting all 3? (4 if you count the G scale I want to set up in the backyard as well. ) I just feel like I'm betraying my old Lionel by going to another gauge. I know it sounds goofy but that old O27 was with me though the better part of my childhood and early/mid teens. Anyone else get overly sentimental for their old trains?
