For a long time I have tried to buy from US firms, but for more than a few years, while faced with an ongoing decline of the US, I have been happy if I can just avoid buying things from China. Maybe that will now change, and one can possibly have some hope.

Badmother, you may have a better point than you can imagine. I will likely explore that avenue while also considering borrowing my wife's Speed D7 for my next effort. In the event that I need to use the Dahon and I also succeed in the effort, any articles I write will only generically refer to using a "folding bike".
