Sounds like fun. I wouldn’t worry about the stuff from Japan, they’ve got things pretty well under control there.
As for the geep, sounds nice. Hope you got an Atlas or Kato. For N scale, I think I’m happiest with my Kato locos. They make good stuff, especially the 2-8-2’s.
The loco I bought was manufactured by Atlas. I already had (and still have) a GP20 made by Life-Like, but I am planning a protolance layout on the Southern Pacific (the GP20 is in UP colors).
And I HAD to have this particular GP9, because it’s in SP Black Widow paint. :)
Oh, and as for the Unitrack I have coming from Japan, my only real concern about that is I won’t have it until some time in April.
