Looking for opinions from anyone who has purchased any of the budget N scale signal mast from eBay (China). I am in the process of adding signals to my N scale layout and I will need a bunch to do it the way I want to. I know they will not compare with a nice brass mast but neither does the price. My main question is about the LED's. I will probably be shopping for a 2 color (red/green) version rather than the three color version. Some of the pictures I saw made the green look almost like it was yellow. Also, how difficult would it be to remove the LED and install my own? Comments? Which one did you use?
