Buy locally and you won't have to pay the extra 30%-100%, problem solved.
I buy the parts I sell from the EU. Know why? Because no one here in the US is willing to spend $10 million on the machinery to manufacture parts, that might sell for $5000.00 a year.
No one else, here in the US is willing, at all, to do it. I know this because I've checked. The people who can do it, want a minimum of $50,000.00 a year order, with a 5 year guarantee.
Buying from the EU was working out great. I found someone who was turning out high quality parts, at reasonable price, without a minimum order. The worst part was shipping.
Now, thanks to Mr. Wonderful, I have to deal with a 15% increase, longer customs hold times and higher shipping costs. I'm not eating that, I pass that along to the customer.
So, it's not as simple as buy locally, ya pud.
