Another good video, Chris.
I've found some neat items at Nicholas Smith, not always advertised on their website, but just luck of the draw, as they found them in their warehouse and put them out amongst the myriad items. I am sure I missed a lot, too, as I only can get down there a couple times a year.
Before Lionel's BTO Program, Nicholas Smith train shelves were the place to see the items that would stay in stock for a few years at least. They still have in-demand items, however, as shown in your video.
