Eternal optimism....
I will share this on the S scale Facebook page. We have over 800 members now.
For me:
1. Anything scale dimension and detailed. Specifically passenger cars with detailed interiors and LEDs.
2. Anything scale dimension and detailed. Steam: Hudson, Mikado, Pacific, 4-6-0, 2-6-0. Diesel: GP30, GP 7/9, GP40-2, SD40-2, Also S2/4, 44Tonner, 70Tonner, E7, PA, FA
3. Numbered turnouts (#4,#5,#6) and curved turnouts (Ex. 27"r/20"r)
Everything should be made Hi-Rail and Scale compatible if possible.
