Hi Lester,
Two you missed:
Raily :
Building your own: Templot or Trax2.
Buying ready-made: Any of the others. XTrkCad is free. AnyRail is the easiest. 3rd PlanIt is far and away the best, with full 3D visualisations and train running simulation. But hopeless if you want track construction templates for building.
regards,
Martin.
