We share this concern of course. The Reform Next shipments are quite a while in the future and I’m sure the situation will develop significantly until then. We’ll also be in touch with CS/Mouser about this.
Side note about US based MNT assembly: In a different political climate, I’d be totally considering to do some assembly in the US. I even had some discussions about this with Cyber City Circuits back in the day, for example. But the prices for US local manufacturing are really quite high, higher than a 20% tarrif. And you’ll still have to import many of the components.
At this moment, I think it’s best to wait a bit until the dust settles.
