I got out of Standard Gauge just because I had some $$ tied up in trains that I really couldn't run or enjoy: too little room, time, etc. I remain very interested in SG trains. Should the room, time, etc., ever materialize, I will get back into it.
HOWEVER: I only have interest in originals, and I have zero interest in anything MTH.
I wonder how many hobbiests are in a similar position.
