There’s another topic on this (Collective sticks for helicopters?) that I recommend you look at due to the niche nature of helicopter controls. I recommend doing a decent amount of your own research to find what might be best for you; as lower sales volume generally means higher cost, this becomes a bit of a buy-once-cry-once situation.
As I live in the US, I ended up recently going with a Virpil one, as they opened up a US branch with a warehouse IIRC somewhere around Tampa, FL, so that avoided having to deal with the export/import issues as well as potentially making any warranty stuff easier. I still haven’t actually used it yet (though I’ve updated the firmware and made sure all the axes and buttons are recognized in MSFS), but am hoping to soon when SU11 drops.
