WingWin will have to get some certificates (like CE approval and that costs money) to be able to sell the HOTAS in the EU. They will have to pay handling fees and the slow boat transport from China, too. All that will have to be payed by the customer in the end. So I don't think it will get much cheaper than self import in the end.
Wingwin stated they will find an EU warehouse to sell their product, so eventually we will be able to compare prices.
I'll order directly from them.
