I hear you. I think I may have one last MTH RailKing I'll buy while I can, and a set of passenger cars. But then it's LC+. I'm also a toy train guy and not a modeler, so there are certain LC Starter Sets that knock me out and I buy, particularly passenger sets. That Blue Comet Lionchief set from a bit back was a real winner, as was the Santa Fe set.
Yep, there's a lot to be said for the LC and LC+ (1 and 2) offerings. I really like my LC+ Mikado....it does 95% of what I use TMCC for.....remote, coupler, crew talk, bell. Same for the LC Thomas set we bought years ago. Winners!
I was all Lionel until a couple years ago when I saw my brother-in-laws Premier and got hooked on MTH, especially for the speed control and 4 chuffs. When I saw I could get that in Rail King for my smaller layout, I jumped into DCS even though I had no permanent layout (in progress). They've only seen carpet central around the Christmas tree, but I love them. If MTH was staying around, I might've started replacing my old TMCC with PS3 RKs, but not now, at least not unless someone picks up the RK line.
Could be a lot worse. These are "first world problems" and I'm grateful for what I have.
