Try: 4 Nscale (Rio rande Hobbies) is one place, there are a few more, but they always seem to have what you need and at a discounted price. :thumb: :thumb:
I like dealing with Brooklyn Locomotive Works..They have great service and great prices..Of course we all have our favorite on line dealers just like we have our favorite local hobby shop...
I use Model Train Stuff http://www.modeltrainstuff.com/nscale/index.html They always have what I need at the best price on the web. They have always come through with orders on time and had very good service in the event you have questions.
