Been meaning to post this. . .
When hubby and I were in Minnesota last weekend, we stopped at the local Hobby Lobby. In the train aisle were a bunch of tubes filled with various figures (the brand was Toob), such as farm animals, sea life, etc. There were a number of sets with figures in them, such as Jamestown Settlers, Indians, Wild West, and more. The figures appeared to be around 1:32. Each tube cost $8 and had maybe a dozen figures in it–pretty good deal. I imagine they could be modified and spiffed up easily.
