My first post to the forum.  I am planning on standardizing on the new couplers that come with the Spectrum 1:20.3 rolling stock.  Does any one know where I can purchase these couplers as I want to refit my AMS cars and my Bachmann engines (4-6-0, 2-6-0, 45 tonners). I had a fellow in my railroad club make me an uncoupler device and in tests it works best with the Bachmann couplers.  I plan on having a layout with operation so need to be able to couple and uncouple with some degree of reliability.  To date I have found the new Bachmann couplers to be the best.
