US supplier has always been an option, but they've always been 3-5x the cost. This still gets tricky because even if I were to find a US supplier for the raw circuit boards and the assembly labor, the majority of the components on my board do not have US manufacturer alternatives, so there will still be a tariff on those when the US supplier purchases them, and that cost will of course get passed on to me. So I would expect US suppliers to still be 3-5x this price, if not even more.
Thinking about this makes me feel physically ill, so I'm not going to make any decisions right now, but this is a big enough deal that I will have to make some decisions, it's not something I can just ignore.
