Only Spin Drier One Would Consider Importing From Europe
Would be a vintage or perhaps new Miele, or older Frigidaire. Otherwise feel the modern "laundry alternative" one got for a few dollars on fleaPay is fine.
One thing about modern spin dryers is that the plastic bits inside and or including the braking systems are noisy. Brakes are now mandatory IIRC for spin dryers sold in the EU or UK, as opposed to older units that simply coasted to a stop. Locking lids are also required as well.
Have a strange hunch that spin dryers made within the past ten or so years are fine with either 50hz or 60hz. I mean the demand isn't that great that everyone is making them on their own which leads me to think only one or two major players are cranking these things out for various markets. Given the demand it's not likely different motors are fitted for regions, other than 120v or 230v power that is.
