Where can one in-person test niche electronics like force-feedback flight sim joysticks?

I'm curious about flight sim equipment but its a lot of money to spend on something that is both very subjective and difficult to return after buying. I'm particularly interested in Moza's AB6 or AB9 bases.

Maybe there's some hobbyist store somewhere that has sim stuff, maybe there's people eager to show off their sim pit, who knows. (I'm located in Valais)

Thx for any info
