My LHS, Walker's Hardware Store, is 3mi. from my house. A few years back, after listening to some self-styled specialists and experts on this forum, against my better judgement and the advice of a few well-intentioned naysayers, I bought a Lionel scale FEF. Sure enough, as warned by those voices who had bought the same locomotive, it did "hop" down the tracks, coughing and choking, sputtering, and stopping occasionally for a cigarette, or something or other, it seemed to require. Fortunately, I had purchased that loco loco from Walker's and carried it right back to the store with my disappointment in-hand along with it.
The proprietor did not suggest sending it back to the Lionel, nor did he expect me to do so. Instead, he immediately offered to replace the locomotive, after asking if I wanted to try again or have a full refund. I took the replacement with me, and that locomotive and I have lived happily ever after. Amen.
When I want a new locomotive, I go strictly to that LHS, as does my wife.
Oh, and I have avoided ever having any sort of conversation, on any subject, with those few opinionated "experts" who mocked me for my initial reticence about buying the FEF .
