You can get much more then a 5%-20% higher price from the kind of customers which really care about US production (I mean like government, CIA, NSA, which also get stuff like AMD systems with hyper threading disabled or special treatment wrt. management units in a CPU etc. I don't mean people caring for the US, for that target group, from what I have seen over the years, I guess, 5% can work 20% is tricky).
