Experience with Tuxedo outside of Europe? Or other non american companies?

I'm considering buying a laptop from Tuxedo, but I'm in Australia and I'm not sure how bad that idea is. Does anyone have experience or recommendation? I would not buy from any american company though. Is there a risk to not go through the country, or that I would have to pay a massive tax on it?

I bought 2 lenovos before. It seems to be getting worse for Linux and Amd. My first one was awesome, the second one had so many issues and I have to use a usb wifi and blacklist the internal one, so I probably want to skip lenovo this time, even if I have to pay a lot more.
